Using Your Analyzer

This section discusses the basics of using your analyzer, no matter the specific type of analysis you wish to perform. First we go over analyzer safety, particularly radiation safety. Using an X-ray based analyzer safely is very important, and not difficult, provided you read, understand, and follow these guidelines. Secondly, we outline the startup procedure we recommend for daily use to ensure that your analyzer is performing properly and at its most efficient level.

Radiation and General Safety
This section covers topics related to radiation safety and general safety when using a Thermo
cientific Niton XL3 analyzer. At a minimum all operators of the analyzer should be familiar
S with the instructions provided in this chapter in order to handle the analyzer in a safe manner. In addition to reading the information presented on the following pages, Thermo Fisher Scientific recommends that instrument users participate in a radiation safety and operational training class.

Radiation Protection Basics

The Niton Model XL3t analyzer contains an x-ray tube which emits radiation only when the user turns the x-ray tube on. When the x-ray tube is on and the shutter is open, as during a measurement, the analyzer emits a directed radiation beam - see Figures 1 and 2. Reasonable effort should be made to maintain exposures to radiation as far below dose limits as is practical. This is known as the ALARA (As Low as Reasonably Achievable) principle. For any given source of radiation, three factors will help minimize your radiation exposure: Time, Distance, and Shielding.
The Niton Model XL3p analyzer contains a radioactive sealed source. Radiation from this source is fully contained within the device when not in use and allowed to escape through the measurement window only while the user is analyzing a sample. Radiation emission is controlled by a shutter. The analyzer emits a directed radiation beam (See Figure 1 and Figure

2) when the shutter is open during a measurement. Reasonable effort should be made to maintain exposures to radiation as far below dose limits as is practical. This is known as the ALARA (As Low as Reasonably Achievable) principle. For any given source of radiation, three factors will help minimize your radiation exposure: Time, Distance, and Shielding.
Time
The longer you are exposed to a source of radiation the longer the radiation is able to interact
n your body and the greater the dose you receive. Dose increases in direct proportion to
i length of exposure.
Distance
The closer you are to a source of radiation, the more radiation strikes you. Based on geometry alone, dose increases and decreases with an inverse-squared relation to your distance from the source of radiation (additional dose rate reduction comes from air attenuation). For example, the radiation dose one foot from a source is nine times greater than the dose three feet from the source. Remember to keep your hands and all body parts away from the front end of the analyzer when the shutter is open to minimize your exposure.
Shielding
Shielding is any material that is placed between you and the radiation source. The more material between you and the source, or the denser the material, the less you will be exposed to that radiation. Supplied or optional test stands are an additional source of shielding for analysis. A backscatter shield accessory is also available and may be appropriate in some applications.

Exposure to Radiation

Human dose to radiation is typically measured in rem, or in one-thousandths of a rem, called
illirem (mrem), 1 rem = 1000 mrem. Another unit of dose is the Sievert (Sv), 1 Sv = 100
m rem. The allowable limit for occupational exposure in the U.S (and many other countries) is 5,000 mrem/year (50 mSv/year) for deep (penetrating) dose and 50,000 mrem/year (500 mSv/year) for shallow (i.e., skin) dose or dose to extremities. Deep, shallow, and extremity exposure from a properly used Niton XL3t analyzer should be less than 200 mrem per year, (2.0 mSv per year) even if the analyzer is used as much as 2,000 hours per year, with the shutter open continuously. The only anticipated exceptions to the 200 mrem maximum annual dose are: 1) routine and frequent analysis of plastic samples without use of a test stand, backscatter shield, or similar additional protective measures, or 2) improper use where a part of the body is in the primary beam path. Note NEVER OPERATE THE DEVICE WITH A PART OF YOUR BODY IN THE PRIMARY BEAM PATH OR WITH THE PRIMARY BEAM PATH DIRECTED AT ANYONE ELSE.

Also, consider the use of protective accessories such as a shielded test stand or backscatter shield (or equivalent) when performing routine and/or frequent analysis of any of the following:
• plastic (or similarly low density) samples,
• thin samples (such as foils, circuit boards, and wires)
• samples that are smaller than the analysis window.

Monitoring your radiation exposure
Individuals can be monitored for the radiation dose they receive by use of radiation dosimetry
evices (dosimeters). Monitoring dose using a dosimeter can be a way of identifying improper
d use and at the same time demonstrating proper use. In some locations, dosimetry is required by regulations and in others it is optional. It is normally required when the user could reasonably be expected to receive in excess of 10% of the annual dose limit. Thermo Fisher Scientific recommends that you determine and obey the local regulatory requirements concerning radiation monitoring of occupational workers.
Dose in mrem
Dose in mSv
500 5
50,000 500

Two common types of dosimeters are whole-body badges and ring badges. Whole body badges are often attached to the user’s torso (e.g., clipped to the collar, shirt pocket, or waist as appropriate). A ring badge is worn on the finger as a measure of maximum extremity dose. When worn, the specific location of the dosimeter should be that part of the body that is expected to receive the highest dose. This location will depend on how the analyzer is used and so it may not be the same for all users. Dosimetry services are offered by many companies. Two companies offering dosimetry services in the USA and much of the world are:

Pregnancy and Radiation Exposure

International guidance documents (e.g., ICRP Publication 60 and NCRP Publication 116*) recommend that the radiation dose to the embryo/fetus of a pregnant woman should not exceed a total of 500 mrem (10% of normal radiation worker limit) during the gestation period. While this dose limit exceeds the dose limit to a trained operator, pregnant workers may want to take special precautions to reduce their exposure to radiation. For more information see the U.S. NRC Regulatory Guide 8.13 "Instruction Concerning Prenatal Radiation Exposure" which can be found on the resource CD.
* The International Commission on Radiological Protection, ICRP, is an independent Registered Charity, established to advance for the public benefit the science of radiological protection, in particular by providing recommendations and guidance on all aspects of protection against ionizing radiation.
* The National Council on Radiation Protection and Measurements (NCRP) was chartered by the U.S. Congress in 1964 as the National Council on Radiation Protection and Measurements.

How to Use the Niton XL3t Analyzer Safely

The Niton XL3t analyzer is designed to be safe to operate provided that it is used in
ccordance with manufacturer's instructions. Under conditions of normal use, monitored
a operators seldom receive a measurable dose and have not been known to receive in excess of 10% of the annual occupational dose limits (a criteria that would require monitoring under regulation in the U.S.). In addition to proper use of the XL3t, it is recommended that you follow these precautions to ensure your safety and the safety of those around you.
Know where the beam is
The primary beam is a directed beam out of the front of the analyzer that can have high dose
ates. The secondary beam, or scattered beam, has much lower dose rates.

Handle and Use with Respect

Avoid holding the front of the analyzer when the x-ray tube is energized and the shutter is
pen. Never point the instrument at yourself or anyone else when the shutter is open and the
o x-ray tube is energized. Never look into the path of the primary beam.

Follow a Radiation Protection Program

Your organization should establish, document, and follow a Radiation Protection Program. An example of such a program can be found on the resource CD (provided with the instrument).

Take Proper Care of your Niton XL3

Keeping your analyzer maintained in good condition will help minimize the risk of accidental exposure. Mechanical malfunction of the shutter can be avoided by maintaining the measurement window, as described in the User Guide. This prevents foreign objects from entering your analyzer

Avoid Over-Exposures

Direct contact with the window could result in overexposures in the times indicated inTable 4 below.

*Based on maximum deep dose rate and US exposure limit.
Safe Handling of Samples
As mentioned many times in this chapter, never place any part of your body in the path of the
-ray beam. There is always a safe way to handle samples whether they are small, irregularly
x shaped, or of low density. Never look into the path of the primary beam.
5 rem (50 mSv) 2.1 minutes
50 rem (500 mSv) 0.95 minutes
0.1 rem (1 mSv) 2.5 seconds*

Small Samples

A small sample would be any sample that is smaller than the measurement window. Small samples present a unique risk because they don’t block the entire beam path. The difficulty with placing small samples down on a work surface to analyze them is that you may get readings from the work surface that interfere with analytical results. A test stand is an effective way of analyzing small samples accurately and safely. Never hold samples during analysis or look into the path of the primary beam.

Irregularly shaped samples may not allow the proximity button to be depressed, or they may not entirely cover the primary beam and cause additional scattering. A back scatter shield is a safe way of reducing your radiation exposure while effectively analyzing an irregularly shaped sample.

Low Density Materials (such as plastics).

X-rays are attenuated more through denser materials and less through low density materials
uch as plastic. This causes higher dose rates in the scattered radiation. If you are frequently
s handling low density samples, you should consider the use of test stands, backscatter shields, or the equivalent.

Primary Radiation

Primary Radiation
Niton XL3t and XL3t GOLDD
Primary radiation is radiation that is produced by the analyzer and emitted out through the measurement window. Individuals should never place any part of their body in the primary beam path when the x-ray tube is on. There should always be a sample in contact with the measurement window when the x-ray tube is on. The sample will absorb most of the primary-beam radiation unless it is smaller than the instrument's measurement window or of low density and/or thickness. Caution should be taken when analyzing samples that are small, thin, and/or low in density as they may allow much more of the primary beam to escape. In-beam primary radiation dose rates are listed in Table 1-6, 1-7, 1-8, 1-9, and their location identified relative to the analyzer in Figure 4 as Dose Point C.
Niton XL3p
Primary radiation is radiation that is produced by the analyzer and emitted out through the
easurement window. Individuals should never place any part of their body in the primary
m beam path when the shutter is open. There should always be a sample in contact with the measurement window when the shutter is open. The sample will absorb most of the primary-beam radiation unless it is smaller than the instrument's measurement window or of low density and/or thickness. Caution should be taken when analyzing samples that are small, thin, and/or low in density as they may allow much more of the primary beam to escape. In-beam primary radiation dose rates are listed in Table 1-6, 1-7, 1-8, 1-9, and their location identified relative to the analyzer inFigure 4 as Dose Point C.

Secondary Radiation

Under conditions of normal and proper use, individuals can be exposed to secondary (or
scattered") radiation. Secondary radiation is low-level radiation that emanates from the
" sample being analyzed as a result of primary beam radiation scattering in the sample or primary beam radiation inducing fluorescent x-rays in the sample. Dose points A, A’ and B in Figure 4 are examples of where you can encounter secondary radiation. The magnitude of this secondary radiation is sample dependent. Higher density samples such as steel will emit the lowest levels as they absorb most primary and secondary radiations. Lower density samples such as aluminum, wood, and especially plastic, will produce higher levels of secondary radiation.
Niton XL3t and XL3t GOLDD
Secondary radiation dose rates are listed in Tables 1-4, 1-5, 1-10, and 1-11, for a few common sample types over a wide range of densities.
22 Niton XL3 Analyzer User’s Guide Thermo Scientific
Page 31
Niton XL3p
Secondary radiation dose rates are listed in Tables 1-13 and 1-14 for a few common sample types over a wide range of densities.

Holding Samples

The operator is reminded that one should never hold samples during analysis, doing so will
esult in higher than necessary exposure to secondary radiation and could expose the operator
r directly to the much higher primary-beam dose rates.

Deep and Shallow Dose

You will find in the tables that shallow dose rates are listed for some dose points. All dose rates listed in the In-Beam Primary Radiation Tables are deep dose unless they are specifically identified as shallow dose. Deep dose is dose from penetrating radiation that is delivered to both skin and underlying tissues and organs and is the type most commonly referred to when describing external radiation hazards. Occupational deep dose is limited to a maximum of 5 rem (50 mSv) per year in the United States and most countries internationally. Deep dose is measured at 1.0 cm below the skin surface.
2
Using Your Analyzer
Deep and Shallow Dose
Shallow dose is often referred to as "skin dose" because it is a result of low penetrating radiation that only interacts with the skin. Shallow dose is limited to a maximum of 50 rem (500 mSv) per year in the United States and most countries internationally. Shallow dose is listed for primary in-beam dose points only because the low penetrating radiation that causes shallow dose is nearly all absorbed by a sample and does not produce any significant secondary radiation. Shallow dose is measured at a point 0.007 cm below the surface.

Proper and Improper Operation

Storage and Transportation

Storage
Regulations in nearly all locations will require that you store your analyzer locked in a secured
rea to prevent access, use, and/or removal by unauthorized individuals. Storage requirements
a will vary by location, particularly with regard to storage at temporary job sites or away from your primary storage location such as hotels and motels and in vehicles. You should contact your local Radiation Control Authority to identify the specific storage requirements in your jurisdiction.

Transportation
Niton XL3t and XL3t GOLDD
There are no X-ray tube specific US Department of Transportation (DOT) or International Air Transport Association (IATA) radiation regulations regarding shipping the Niton XL3t analyzer. It is recommended that you ship the analyzert in its carrying case and an over-pack to protect the sensitive measuring equipment inside the analyzer. Do NOT ship the analyzer with the battery pack connected to the analyzer.
Niton XL3p
For Thermo Fisher Scientific, Niton Analyzers (Niton Analyzers), in the United States, the
overnment agency that has primary authority and regulations which apply to transportation
g is the Department of Transportation (DOT) (Code of Federal Regulations 49 Parts 100 to
185).
In addition, the EPA, OSHA, and the NRC also have regulations that touch on the transportation of hazardous substances.
The International Air Transport Association (IATA) has recommendations that every major air carrier has incorporated into their policies for the air transport of hazardous substances.
The enforcement of DOTregulations is carried out by the Department of Transportation, the Federal Aviation Administration, the Federal Highway Administration, the Federal Railroad Administration, the Coast Guard, and Customs and Border Protection. State agencies may also enforce state DOT regulations.
The major aspects of the regulations include:
• "training to recognize hazards and how to safely deal with hazardous substances,
• "classification and identification of packages to inform of hazards,
• "protective packaging to safely transport hazardous materials,
• "hazard communication to inform personnel of hazards in a package,
and
• "incident reporting to inform regulators of incidents.
As part of shipping hazardous substances, you should be trained in:
• "a general awareness and a familiarity with the general provisions of the DOT and hazardous materials regulations,
• "training that is function specific and be applicable to the daily work performed,
• "the recognition and identification of hazardous substances,
24 Niton XL3 Analyzer User’s Guide Thermo Scientific
Page 33
2
Using Your Analyzer
Proper and Improper Operation
• "the specific requirements for functions performed,
• "security measures to keep a package secure.
• "safety issues as related to safe handling and hazard communication.
• "knowledge of emergency response information, self-protective procedures, and accident prevention procedures.
Employers are responsible for providing the proper training (every three years for DOT) to employees, testing employee knowledge, and record keeping.
The DOT Hazardous Material Regulations set the criteria for determining the hazard class and the proper shipping name for hazardous materials. The Hazard Classes as follows:
Class
1. Explosives
2. Gases
3. Flammable and Combustible Liquids
4. Flammable solids, combustible materials, and dangerous when wet materials
5. Oxidizers and organic peroxides
6. Toxic materials and infectious substances
7. Radioactive Materials
8. Corrosive Materials
9. Miscellaneous dangerous goods
Niton analyzers with radioisotopes are Hazard Class 7. The Hazard Class of the material being transported tells you which Parts of the regulations are required.
A UN number is assigned to each type of hazardous material. It is the letters "UN" followed by a four digit numerical code, which allows emergency responders to identify the chemical being shipped. The UN number for Niton analyzers is "UN 2911".
There is also an official name designation for Niton Analyzers called the Proper Shipping Name. The proper Shipping Name for the Niton Analyzers is "Radioactive material, excepted package-instruments and articles".
A reportable quantity (RQ) is listed in DOT regulations for each hazardous material (e.g., each radioactive isotope). If you are shipping more than the reportable quantity in a package, that package must be marked clear and legibly with the letters "RQ". The Niton XL3p analyzer contains a 30 mCi (1.11 GBq) Am-241 source and is therefore considered a reportable quantity requiring the RQ marking when being transported.
Thermo Scientific Niton XL3 Analyzer User’s Guide 25
Page 34

Using Your Analyzer
Proper and Improper Operation
Also, the quantity of Am-241 that is used in a Model XL3p Analyzer requires a special form certification for transport as an excepted package. This Special Form certificate must accompany the instrument during shipment. Thermo Fisher Scientific will provide the Special Form certificate for any analyzer with Am-241.”
The type of protective packaging used is dependent on the nature of the material to be packaged. All packaging must be designed to prevent a release of hazardous material during normal transportation or storage of the material. The classification of package used for Niton Analyzers is designated as an "Excepted Package". Always ship the analyzer in its original plastic case to ensure that the packaging used meets the regulatory requirements for an Excepted Package.
Shipments of radioactive materials must have proper Labeling and Marking.
Niton analyzers have a Marking requirement (i.e., UN number and RQ if applicable), but not a Labeling requirement (i.e., diamond shaped hazmat labels), and vehicles transporting these analyzers are not required to have "Placards".
When reading the DOT regulations, you will find the following information useful.
Thermo Fisher Scientific, Niton Analyzers are shipped:
• "Under the proper shipping name "Radioactive material, excepted package-instruments or articles" in accordance with 49 CFR 173.424,
• "with the radiation level at 10 cm from the unpacked instrument surface less than 10 mrem/hr (0.1 mSv/hr) “ Note A Niton Analyzer in proper condition will be less than 0.5 mrem/hr (0.005 mSv/hr) at 10 cm,
• "with the radiation level at the package surface less than 0.5 mrem/hr (0.005 mSv/hr)” Note A Niton Analyzer in proper condition will be less than 0.05 mrem/hr (0.0005 mSv/hr) at the surface of the case,
• "with all radioactive sources as "solid", "sealed sources"
• "Am-241 listed in A1 column of 173.435 (270 Ci) (Special Form capsule)
• "with the package design meeting the requirements of 173.410
• "package marked with "UN2911"
• "with the Am-241 source, the package is marked with "RQ"
• "meeting the 173.424 criteria for labeling and marking requirements
For any shipment: Include in the package a current copy of the instrument Leak Test.
Include a list of emergency numbers in the package.
For Am-241, include the Special Form Certificate in the package.

Proper and Improper Operation
Always ship in supplied plastic case, with the case secured against accidental opening. Always ship with the battery disconnected.
When shipping by air: Ship with the proper IATA marking (See IATA Dangerous Goods regulations Figure 10.7.8.A), UN 2911, and proper shipping name.
"RQ" marking and "dangerous goods declaration" are required.
When shipping by Ground: Ship under proper marking "UN2911"
"RQ" marking and shipping papers are required (Note: a dangerous goods declaration form can be used to meet the shipping paper requirement).
A "Dangerous Goods Declaration" can be obtained by the air carrier that you will be using. Instructions can also be obtained from the same source.
Carefully follow the directions given by the air carrier. Several typed copies will be required.
Shipping papers contain all of the same information as a Dangerous Goods Declaration, but do not have a specified format for that information.
At a minimum, a properly prepared shipping paper clearly identifies the hazardous substance by its proper shipping name, hazard class and division, UN identification number, packing group (if applicable), and total quantity. It also has consigner information, consignee information, and a shipper's declaration that the package is in compliance with the DOT regulations.
The elements of hazard warning information are communicated through shipping documents, packaging markings, and written emergency response information.
The DOT & FAA Hazardous Materials Regulations require the carrier to report all incidents involving hazardous materials.
An "incident" involves the unintended release of hazardous materials (Am-241), suspected radioactive contamination, if the general public is evacuated for an hour or more, or the flight pattern or routine of an aircraft is altered.
For any "incident", contact the Company Radiation Safety Officer or Responsible Party and the state radiation control program.
Any "incident" needs to reported to the:

Leak Tests (Niton XL3p Only)
The Niton XL3p Series analyzer contains a radioactive source that must be periodically leak tested. The purpose of leak testing is to verify the integrity of the source encapsulation. A leak test sample is obtained by wiping exterior surfaces of the device with moderate pressure using a cotton swab, filter paper, or whichever wiping media is supplied by the analysis laboratory. Leak test samples are then typically analyzed at a laboratory, although some device users have the equipment and licensed authority to perform this analysis
Unless specified otherwise by your local authority or radioactive material license, the gauge must be leak tested at intervals not to exceed 6 months. In the US, leak test samples may be acquired by any end-user, however the analysis of the sample must be performed by an organization licensed to do so. If you are using a vendor to perform the laboratory analysis of the leak test sample, they will send you a leak test kit which comes with complete instructions for performing the test. These vendors will also typically send you a reminder when it is time to perform the next leak test on your instrument. Please follow the test kit instructions carefully, and promptly mail the test samples to the laboratory. They will send you a leak test certificate soon after. Keep one copy of the leak test certificate with the device at all times (i.e., in the case) and another copy safely on file.

The Control Panel

The Control Panel
The control panel is located on the analyzer’s top housing, directly below the Touch Screen. The control panel consists of a 4 Way Touch Pad, an Interlock Button, and two Control Buttons, one on each side. Using either the control panel or the touch screen you may navigate through all of the analyzer’s screens and menus. You can control the movement of the screen cursor by pressing the 4 Way Touch Pad in one of four directions to highlight each of the menu options. The Clear/Enter button to the right of the 4 Way Touch Pad is used to select highlighted menu options. The On/Off/Escape Button both controls the power to the analyzer and serves as an "escape" button. When the On/Off/Escape Button is pushed and immediately released, it functions as an "escape", and brings you back to the Main Menu from the current screen in the menu system.
Figure 14. The Control Panel
To turn your analyzer on, push and hold the On/Off/Escape Button until the Touch Screen comes on. To turn off your analyzer, push the On/Off/Escape Button and hold it down until the Touch Screen shuts off. CAUTION If for any reason your analyzer does not shut off normally, removing the battery will shut it down safely.
You also have the option of operating the analyzer, including navigating the menu system, by using the built in Touch Screen. To select a menu option, tap on the icon once. The touch screen icons have the same functionality as the 4 Way Touch Pad, the On/Off/Escape Button, and the Enter Button. This User's Guide will refer to the process of choosing a course of action by selecting an icon from a menu, either using the Touch Screen or using the control panel buttons, as “selecting.”
Selecting the Return Icon works everywhere throughout the User Interface to bring you back to the previous menu from the current menu in the menu system. Use the On/off/escape button to return to the Main Menu.

Using Your Analyzer
The Results Screen
The Nominal Seconds Test Duration line shows the number of nominal (source) seconds elapsing since the initiation of the reading. Nominal seconds are instrument time designed to compensate for the electronic dead-time that may occur when your analyzer is taking a measurement, and therefore tend to be a bit slower than real time.
The Mode displays the test mode in use during the measurement.
The Match/No Match line indicates whether your analyzer has found a matching alloy in it's library for the sample you have measured, and displays the name(s) of any matching alloys and the Match Number (chi squared deviation).
The Element (left) column shows the elements that have been detected in the sample.
The Concentration Level (central) column shows the concentration levels of the corresponding elements in percentages.
The Confidence (right) column displays the 2 sigma (95%) confidence interval for the corresponding elements.

Match Number

If there are too many elements detected to fit onto a single screen, you can see the balance of the elements and their results (as in figure 3-16) by pressing the down arrow of the 4-way touch pad. To see previous results, use the left arrow of the 4-way touch pad. To go forward to later readings, use the right arrow of the 4-way touch pad.
The Match Number is a rating of confidence in the identification of the alloy. The Match
umber ranges from 0.0 to 10.0, with 0.0 being a perfect match. Any number greater than
n
4.0 gives a result of No Match by default, although you can change this match threshold. Any
number less than 2.0 is considered a Good Match, and can usually be brought closer to 0.0 with longer testing times. Numbers between 2.0 and 3.0 can be considered Probable Matches, and numbers between 3.0 and 4.0 as Possible Matches, often having one or more elements out of spec.

From the Main Menu, select the System icon, then the Specs icon. The date will be displayed for verification. If the date is incorrect, correct it prior to proceeding. This can be done by “Closing” out of the Specs screen and selecting the Date & Time icon. Detailed information on this procedure is available in Setting the Date and Time.
(Optional) Connect the analyzer to a computer via the included serial cable, USB cable, or Bluetooth™ wireless module. (Consult “Using Your Analyzer With Your PC” on page 151for
tails, if necessary.)

During analysis and detector calibrations, it is important to ensure that the analyzer is not exposed to strong electromagnetic fields, including those produced by computer monitors, hard drives, cellular telephones, walkie talkies, etc. Keep a minimum two (2) feet (0.7 meters) distance between the analyzer and electronic devices.
From the Main Menu, select System Check icon then the Yes button. (Figure 1.)
System Check calibrates the detector and verifies it is operating to specifications. After starting the process, no further user interaction is required during this operation. When the instrument is finished performing the check, the unit will show either “System OK” or one of the failure errors.
If the unit shows a failure error, then perform a second System Check by clicking Recheck. If the unit still does not show a “System OK,” please contact Thermo Scientific Niton Analyzers toll-free in the USA at (800) 875-1578, +1 978 670-7460, niton@thermofisher.com, or contact your local Niton Analyzers representative for assistance.
Figure 41. System Check Menu Path
Thermo Scientific Niton XL3 analyzers are equipped with excitation filters that optimize the analyzers’ sensitivity for various elements. The “Main Range” filter provides optimum sensitivity for the elements manganese (Mn) through bismuth (Bi). The “Low Range” filter is used to optimize the sensitivity for the elements from titanium (Ti) through chromium (Cr).

How to Analyze
General Analysis
Note that the main range filter can be used to analyze Ti, V and Cr, but the sensitivity is not as good as when using the low filter. The "Light Range" filter is available only with He-purged and GOLDD technology analyzers, and is typically used in light element analysis. The amount of time that the analyzer spends in each filter position is user definable, but the default settings should be used unless there is reason to change them. Please note that the analyzer will continue alternating excitation filters until the user selectable maximum analysis time is reached or the operator terminates the measurement.
Figure 42. Setting Element Ranges
Verify instrument measurement accuracy using the supplied reference material (RM) supplied with the analyzer.
Test the factory-supplied reference standard (or other approved check sample) based on a 30s measurement using main range filter only. If the sample is correctly identified and all major elements read within calculated acceptance limits (within the low and high values of factory readings found on the QC sheet, proceed to General Testing Protocol section
If the analyzer reports values outside the acceptance tolerance ranges specified in the tables, repeat the detector calibration then repeat the reference sample analysis.
If the analyzer again fails to meet the acceptance tolerance ranges specified in the tables, please contact Thermo Scientific Niton Analyzers or your local representative for assistance.

GENERAL TESTING PROTOCOL

Good surface preparation is essential for obtaining accurate test results. All non- representative
aterial (e.g., paint, coating, scale) must be removed prior to testing. An approximately
m 2-inch-square section of surface should be cleaned down to the material to be analyzed. See the Resource Guide for information on Sample Preparation.
68 Niton XL3 Analyzer User’s Guide Thermo Scientific
Page 77
The analyzer will often display a correct alloy identification and/or accurate chemistry result before the specified time interval. If the accuracy meets the user’s requirements, it is not necessary to measure for the full time.
Longer measurements might be necessary if low concentrations of elements must be determined.
INSTRUMENT QC
Measure the supplied reference calibration check sample AT LEAST once a shift. If correct, continue work. If incorrect, redo System Check and re-take the past 2 hours of results.

UNDERSIZED OR NON-CONTACT SAMPLES

(Samples that do not make contact with or that do not fully cover the measurement aperture)
or samples that do not fully cover the measurement aperture, increase the testing time by
F increasing the time in inverse proportion to the decrease in percentage of aperture covered. For example: a rod only covers ½ of the aperture, so increase the measurement time by two (e.g., from 10 to 20 seconds per filter for alloy chemistry).

How to Analyze
General Analysis
The best procedure to measure undersized samples is to use the Thermo Scientific Niton portable test stand (optional), which is shielded to prevent radiation exposure to the operator.
An undersized sample may alternately be measured while lying on another material. Results may be affected by the signal coming from the underlying material itself. Use only pure aluminum, pure plastic, or clean wood and employ the Disable Al feature. Use the Tools Menu, then select Disable Al, and check the underlying surface itself to be sure no metals are present. Be sure to use the Tools Menu and select Enable Al before testing aluminum alloys.

TestAll Geo Mode

Use this mode to analyze powder, mineral, and ore samples without first determining whether the samples would best be analyzed with Mining or Soil Mode. This mode uses both the Compton Normalization calibration (Soil) and the Fundamental Parameters calibration (Mining) to determine whether the soil calibration is acceptable or whether the total metal content is too high for Compton mode. It will then return an elemental composition of the sample as analyzed. If the sample can be analyzed via soil mode, then the analyzer will display results from both Soil and Mining Modes in one unified list. If both calibrations contain the same element, then the mode that has the lower detection limit will be displayed. Material Elemental Composition is outputby default in terms of both parts per million (mg/kg) and percent of composition by weight, with 0.10% being the cutoff point.
Note Due to the nature of this mode, your analyzer will only use factory calibrations. User modified Cal Factors will not be available.

Common Operations

Metal Sample Prep

Up until recently, sample preparation was not a big worry for XRF metals analysis, as the
OD of the analyzer was seldom low enough for any but the most heavy contamination to be
L intrusive; but recent developments such as He-purged analysis have brought analysis to a level where even light surface contamination can skew an analysis.
You should always prepare your samples before analysis, especially when using He-purged analysis, as these analyzers will see even trace amounts of contaminants. Oils from fingerprints and other body contact, lint, oxidation materials, and abrasive materials used in cleaning can all skew readings if not removed. Sample preparation is simple and not time consuming, and usually well worth the effort.
The following is a list of problems that need correction before testing:
5
Common Operations
Metal Sample Prep
• Oxidation or Rust may produce an increase or decrease in one or more element test values unless we remove the rust or oxidation and expose the raw metal.
• Paint may contain several elements which need to be tested at lower levels within metal alloys (Ti & Zn in white paint, Fe in red paint, Cr in green paint).
• Oil, grease or lubricates may contain high levels of the following elements: lithium, aluminum, barium, strontium, molybdenum or calcium.
Plated surfaces may have high levels of the following elements: zinc, chromium, nickel, or copper.
CAUTION Anything on the metal surface will become part of your test results!

Sample Analysis Preparation

You need to clear the surface of your samples of any paint, plating, or any oxidation such as
ust or verdigris before analysis. In order to accomplish this, you need the following:
r
• Isopropyl alcohol - not rubbing alcohol, which contains oils.
• Lint-free paper.
• Diamond paper - P/N 179-1202- cut into 1 inch/2.5 cm squares. Never re-use this paper, as it may transfer contaminants to the surface of the sample from previous cleanings. Depending on the state of the sample, several squares may be needed per sample.
Thermo Scientific Niton XL3 Analyzer User’s Guide 89
Page 98

Common Operations
Metal Sample Prep
• A Sample Grinder for removing deeper surface contamination. Choice of grinding wheel media also may be important, depending on what you are testing for. Never re-use grinding media, as contaminants can be transferred from sample to sample on the media itself.
For light contamination on hard metal reference standards, remove the oxidation by scrubbing the dry sample lightly with the diamond paper square, using the fingers to maintain pressure. If the diamond paper begins to load up with material, discard it and use a fresh square. When the oxidation is removed, wipe the sample with lint-free paper soaked with isopropyl alcohol to remove any oils or dust. Let the sample dry before attempting analysis.
For soft metal reference standards, wipe the sample with lint-free paper soaked with isopropyl alcohol, then remove the oxidation by scrubbing the wet sample lightly with the diamond paper square, using the fingers to maintain pressure. If the diamond paper begins to load up with material, discard it and use a fresh square. When the oxidation is removed, wipe the sample again with lint-free paper soaked with isopropyl alcohol to remove any oils or dust. Let the sample dry before attempting analysis.
Oils, lint and dust can be removed by wiping the sample with lint-free paper soaked with isopropyl alcohol. Let the sample dry before attempting analysis.

Surface Oxidation

With the exception of a limited number of metal types, most metal alloys form an oxide
overing on the surface when exposed to oxygen or air. This oxide covering is visible in carbon
c and low alloy steel as a red colored substance called rust. Other metal alloys form oxidation which is not always visible, but that does not mean that it is not present. If the test results for low concentration elements are higher or lower than expected, remove the oxide coating by grinding and retest. Follow proper safety procedures when changing discs or grinding materials.
During a recent case study the effects of sample preparation became apparent. A customer asked for low detection limits of nickel, chromium and copper in carbon steel pipe. The reported chemistry of the purchased material is listed on the first line in the chart below. The test results of a hand held Niton XL3t 900S GOLDD instrument appears in the second line of the chart. The results from a test on the unground surface appear in the bottom line of the chart. Note the values for nickel and copper in this carbon steel alloy in the chart below. The oxidation on the surface of this pipe was not visibly egregious. We need to always be wary of the presence of even low levels of oxidation and their possible effects on analytic accuracy.

Painted Surfaces

Paint is a mixture of several items that are combined into a liquid which is applied to the
urface of materials such as metal. Once applied this liquid dries with time and adheres to the
s surface of metal. Paint is used to protect or decorate the metal item. Paint can also be used to identify or mark the metal during the manufacturing process.
Components of paint are divided into classifications of pigments, binders, solvents, additives and fillers. The inorganic elements in pigments will contribute to increases in displayed values for those elements if paint on the metal surface is not removed prior to testing. Be especially careful of the presence of heavy elements, which can also act to shield x-rays from lighter elements in the metal sample.

Oil, Grease & Cutting Oils

Oil and grease contain a number of elements combined into a viscous substance and applied
o moving parts in order to reduce friction. Grease coatings can remain on component
t surfaces after it has been removed from service. Grease can also be applied to a metal's surface by accidental contact with other materials coated in heavy grease. Metals can also be coated in oil as a result of cutting and machining processes in manufacturing.
Grease and oil may contain the following elements:
• Aluminum (Al)
• Zinc (Zn)
• Molybdenum (Mo)
• Sodium (Na)
• Calcium (Ca)
An experiment was performed to show how grease on metal surfaces affects XRF results. A carbon steel sample was cleaned and ground as a control surface for the experiment. XRF tests were performed on the control surface, and again after light and heavier layers of automotive wheel bearing grease were applied to the surface of the steel sample. Results are shown below. Note the elevated levels of molybdenum, cobalt and zinc from the grease.
