In case you have any problems with your moisture analyzer:

$ contact your local Denver Instrument

office, dealer or service center

Warning: Severe Burns!

– When setting up the moisture

analyzer, leave enough space to prevent heat from building up and to keep your analyzer from overheating: – leave 20 cm (about 8 inches)

around the moisture analyzer

– 1 m (3 ft.) above the device

– Do not put any flammable

substances on, under or near the moisture analyzer, because the area around the heating unit will heat up

– Be careful when removing the

sample from the chamber: the sample itself, the heating unit and the sample pan used can still be extremely hot

– Do not remove the heating unit

during operation: the heating element and its protective glass panels can get extremely hot!

– Prevent excess heat build-up

around the analyzer

Hazards for persons or equipment posed by using specific samples:

Fire Explosion

– Flammable or explosive substances – Substances that contain solvents – Substances that release flammable

or explosive gases or vapors during the drying process

In some cases, it is possible to operate the moisture analyzer in an enclosed nitrogen atmosphere to prevent the vapor released during drying from coming in contact with oxygen in the surrounding atmosphere. Check on a case-to-case basis whether this method can be used, because installation of the analyzer in too small an enclosed space can affect its functions (for instance through excessive heat build-up within the analyzer). When in doubt, perform a risk analysis.

The user shall be liable and responsible for any damage that arises in connection with this moisture analyzer.

Poisoning Caustic burns

– Substances containing toxic or

caustic or corrosive substances: These may be dried only under a fume hood. The value for the “lower toxic limit“ in a work area must not be exceeded.

Corrosion:

– Substances that release aggressive

vapors during the heating process (such as acids): In this case we recommend that you work with small sample quantities. Otherwise, vapors can condense on cold housing parts and cause corrosion. The user shall be liable and responsible for any damage that arises in connection with this moisture analyzer.

Warning and Safety Information

The moisture analyzer consists of a heating unit, a weighing system, a display and control unit and a printer. In addition to the socket for AC power (mains supply), it also has an interface port for connecting peripheral devices, such as a PC, an external printer, etc.

The equipment supplied includes the components listed below:

– Moisture analyzer – Power cord – Pan support – Shield disk – Dust cover for keypad – Internal printer – 80 disposable aluminum sample

pans – 1 pair of forceps – 3 cards with brief instructions in

6 different languages

Installation Instructions

The moisture analyzer is designed to provide reliable results under normal ambient conditions in the laboratory and in industry. When choosing a location to set up your moisture analyzer, observe the following so that you will be able to work with added speed and accuracy:

– Set up the moisture analyzer on a

stable, even surface that is not exposed to vibrations

– Avoid placing the analyzer in close

proximity to a heater or otherwise exposing it to heat or direct sunlight

– Avoid exposing the moisture

analyzer to extreme temperature fluctuations

– Protect the moisture analyzer

from drafts that come from open windows or doors

– Keep the moisture analyzer

protected from dust, whenever possible

– Protect the moisture analyzer from

aggressive chemical vapors

– Do not expose the analyzer to

extreme moisture

– Make sure to choose a place

where excessive heat cannot build up. Leave enough space between the moisture analyzer and materials that are affected by heat.

Conditioning the Moisture Analyzer

Moisture in the air can condense on the surfaces of a cold moisture analyzer whenever it is brought into a substantially warmer place. If you transfer the moisture analyzer to a warmer area, make sure to condition it for about 2 hours at room temperature, leaving it unplugged from AC power. Afterwards, if you keep the moisture analyzer connected to AC power, the continuous positive difference in temperature between the inside of the moisture analyzer and the outside will practically rule out the effects of moisture condensation.

§ Check the voltage rating and the plug design

$ The heating unit of the moisture analyzer has been factory-set to 230 or

115 volts for technical reasons. The voltage has been set as specified on your order. The voltage setting is indicated on the manufacturer’s label (see the bottom of the analyzer), for example: – 230 volts: IR120Q-...230.. – 115 volts: IR120Q-...115..

! If they do not match: To have the voltage setting changed, contact your local

Denver Instrument office or dealer, and do not operate your moisture analyzer in the meantime!

Use only – Original power cords – Power cords approved by a certified electrician/Denver Instrument service

technician – If you need to connect an extension cord:

Use only a cable with a protective grounding conductor

§ Connecting the moisture analyzer, rated to Class 1, to AC power (mains supply):

The moisture analyzer must be plugged into a properly installed wall outlet

which has a protective grounding conductor (PE)

Safety Precautions

If you use an electrical outlet that does not have a protective grounding conductor, make sure to have an equivalent protective conductor installed by a certified electrician as specified in the applicable regulations for installation in your country. The protective effect must not be negated by using an extension cord without a protective grounding conductor.

Information on Radio Frequency Interference

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. Changes or modifications not expressly approved by Denver Instrument AG could void the user‘s authority to operate the equipment. The AC adapter rated to Class 2 can be plugged into any wall outlet without requiring any additional safety precautions. The ground or earth terminal is connected to the housing, which can be additionally grounded, if required. The data interface is also electrically connected to the scale housing (ground).

Connecting Electronic Devices (Peripherals)

§ Make absolutely sure to unplug the moisture analyzer from AC power before

you connect or disconnect a peripheral device (printer or PC) to or from the

interface port.

Warmup Time

To deliver exact results, the moisture analyzer must warm up for at least 30 minutes after initial connection to AC power or after a relatively long power outage. Only after this time will the moisture analyzer have reached the required operating temperature.

Charging the Built-in Rechargeable Battery

Before initial operation, leave the moisture analyzer connected to the line current (mains supply) for at least 10 hours to charge the built-in rechargeable battery. When the analyzer is disconnected from line current, the analysis data is retained in memory for approximately three months.

Weighing Function

Purpose

The IR120 moisture analyzer can be used for quick and reliable determination of the moisture content of materials of liquid, pasty and solid substances according to the method of thermogravimetry.

Operating the Moisture Analyzer

Basics

The moisture of a material is often mistakenly equated with its water content. In fact, the moisture of a material includes of all the volatile components which are given off when the sample is heated, resulting in a decrease in sample weight. Among such volatile substances are:

– water – fats – oils – alcohols – organic solvents – flavorings – products of decomposition

(when a sample is overheated)

There are many methods to determine the moisture content of a substance. Basically, these methods can be divided into two categories:

When absolute methods are used, the moisture content is directly determined (for example, as a weight loss registered during the drying routine). These methods include oven drying, infrared drying, and microwave drying. All three of these methods are thermogravimetric.

When deductive methods are used, the moisture content is indirectly determined. A physical property, which is related to the moisture in the substance, is measured (e.g., absorption of electromagnetic rays). These methods include Karl-Fischer titration, infrared spectroscopy, microwave spectroscopy, etc.

Thermogravimetry is the process of determining the loss of mass that occurs when a substance is heated. In this process, the sample is weighed before and after being heated, and the difference between the two weights is calculated.

In a conventional drying oven, circulating hot air warms the sample from the outside to the inside. Efficiency is lost during drying because as the moisture evaporates, it cools the sample surface.

By contrast, infrared rays (IR rays) penetrate a sample without being impeded. Having reached the interior of a sample, they are converted into heat energy, which stimulates evaporation, thus drying the sample. A small part of the IR rays is reflected from the surface of the substance.

IR-Strahlung

Substanz

Wärmeenergie

IR-rays

substance

The quantity of reflected IR rays depends to a great extent on whether the substance is light or dark-colored.

Dark Substance Light Substance Low Reflection High Reflection

How the rays penetrate the sample depends on the sample’s degree of light-transmitting capacity. If the degree of light-transmitting capacity is low, the rays can penetrate only the uppermost layers of the sample. The heat conductivity of the sample dictates the degree to which the heat can be transmitted to the underlying layers. The higher the conductivity, the faster and more uniformly the substance is heated.

The substance should be applied to the sample pan in a thin, even layer. A height of approximately 2–5 mm for 5–15 g substance weight has proved to be ideal. Otherwise, the sample will not be dried completely or the analysis time will be unnecessarily extended, a crust/skin will form on the surface of the sample or the sample will scorch, and the analysis results obtained will not be reproducable, and therefore, cannot be used.

Incorrect Application of a Sample

When preparing a substance for analysis, you should use methods that do not generate heat so that the sample does not lose moisture before it is analyzed.

Perform initial analysis of a new substance to test how the IR rays are absorbed by the sample and converted into heat. The printout of the intermediate values of the drying process provides you with this information at an early stage.

Experience has shown that the temperature setting selected during the infrared drying is usually lower than the temperature setting used when working with a drying oven.

In many cases, the fully automatic shutoff mode will meet your requirements. If the final result is higher or lower than expected, try varying the temperature setting before resorting to a different shutoff parameter.

When analyzing samples that lose their moisture only very slowly or when operating a cold moisture analyzer, the fully automatic mode may end the drying routine too early, if it does not detect any analyzable progress in the drying routine under these conditions. In this case, preheat the moisture analyzer for 2–3 minutes before starting the drying routine or select a different shutoff parameter.

Preparation

Before drying a sample, you must carry out the following preparations:

– Adjustment to the available

measuring system (if required)

– Sample preparation

– Setting the parameters for drying

program

Adjustment to an Existing Measuring System

A moisture analysis method often replaces another drying method (e.g., the oven drying method), because it is simple to use and requires shorter analysis time. In this case, you should adapt this method to that of the moisture analyzer in order to obtain values comparable to those yielded by your standard reference method.

● Perform parallel measurements: take a fresh sample and divide it in half

● Determine the moisture content of the first half using your standard method

of analysis

● Analyze the second half of the sample in the moisture analyzer.

Use the following settings:

– fully automatic mode for the shutoff parameter – lower temperature settings than for the oven drying method – temperature setting for organic substances: 80 – 100°C – temperature setting for inorganic substances: 140 – 160°C

$ If the result for the second part does not correspond to that of the first:

– first, repeat the analysis using a different temperature setting – then use the semi-automatic mode for the shutoff parameter

(such as 5 mg/30 s)

$ Vary the shutoff parameter, if required:

– Increase end-point recognition:

set the parameter to 2 mg/30 s or 5 mg/60 s

– Decrease end-point recognition:

set the parameter to 10 mg/30 s or 5 mg/10 s

Preparing a Sample

Selecting a Sample

● Select a representative part of the whole substance as a sample

– a representative number of individual samples for quality control – samples which indicate a trend are sufficient for in-process control

$ Homogenize the product before a sample is taken, if required, by:

– mixing or stirring – taking several samples from different areas of the product – taking several samples at defined intervals

● Take only one sample at a time for a given analysis and prepare it as quickly

as possible. In this way, it will not lose or gain moisture as a result of the ambient conditions.

$ If you need to analyze several samples at a time, the samples must be sealed

in air-tight containers, in order to be sure that the storage conditions do not alter the state or condition of the samples:

– Warm or highly volatile substances lose their moisture very quickly. – If you store the samples in a container, the moisture can condense on the

walls of the container.

– If the container is too big and not filled completely, the sample can

exchange its moisture with the air remaining in the container.

$ Mix condensed moisture back in with a sample, if necessary.

Preparing a sample

● When crushing a sample, avoid any contact with heat:

heat results in moisture loss.

● Crush a sample with

– a pestle – a shredder (see below)

For liquids containing solids, use

– a glass stirrer – a spoon or – a magnetic stirrer.

$ Use an appropriately designed tool for shredding a sample.

Using disposable sample pans

● Use only Denver Instrument disposable sample pans (order no. 900274-1,

inner diameter = 92 mm). Reusing sample pans leads to poor reproducibility of results:

– after cleaning, sample residues can still remain on the pan

– residues from cleaning agents can evaporate during the next moisture

analysis

– scratches and grooves inflicted during cleaning provide surfaces on which

the rising hot air produced during the drying process can act, resulting in a more pronounced buoyancy

Applying a Sample to the Sample Pan

● Apply the sample to the sample pan in a thin, even layer (height: 2 to 5 mm,

weight: 5 to 15 g); otherwise:

– a sample applied unevenly will result in a nonuniform distribution of heat – a sample will not be dried completely – the analysis time will be unnecessarily extended – the sample burns or a crust/ skin forms on its surface as a result of a very

thick layer

– the crust makes it difficult or impossible for moisture to escape from the

sample during the drying process

– uncertain and unknown quantity of moisture remains in the sample

● Apply liquid samples, pasty samples or samples that can melt to a glass

fiber filter (order no. 900298-1); you will obtain the following advantages:

– uniform distribution due to the capillary effect – prevents liquids from beading together and forming drops – with larger surfaces, the moisture can evaporate faster – considerably more convenient than the “sea-sand method”

When drying samples containing sugar, a crust or skin can form and seal the surface. A glass fiber filter is especially helpful in such cases. The moisture can evaporate downwards through the surface of the filter. You can avoid or limit the crust/skin formation if you place the glass fiber filter on top of the sample.

● Cover solid, heat-sensitive samples with a glass fiber filter

(order no. 900298-1); you will obtain the following advantages:

– gentle heating, because the sample surface is shielded from excessive heat – higher temperature setting can be selected – uniformity of the sample surface – fast evaporation of the moisture – excellent reproducibility for samples containing fat

Avoiding the Formation of Crust/Skin

You can add “solvents” to the sample to prevent the formation of crust/skin during the analysis runs. The weight of a solvent you apply to the sample will not influence the final result of an analysis.

● Once you have closed the sample chamber, open it again within 2 seconds

after you hear a beep tone.

● Apply a solvent to the sample

● Close the sample chamber and start the analysis run as usual

Example 4: Timer Shutoff Combined with Fully Automatic Shutoff Mode

The moisture content of 1.5 g of dispersion adhesive is to be analyzed. While heating, the product forms a skin that makes it difficult for moisture to evaporate from the sample. Increased moisture loss causes this skin to crack, enabling the moisture to evaporate easily again from the sample. To prevent the moisture analyzer from shutting off too early during the initial phase, a minimum time for the drying procedure is entered. The analysis is to be ended automatically as soon as a constant weight is reached.

Weighing System Settings

Calibration, Adjustment

Purpose Calibration is the determination of the difference between the weight readout and the true weight (mass) of a sample. Calibration does not entail making any changes within the weighing system.

Adjustment is the correction of the difference between the measured value displayed and the true weight (mass) of a sample, or the reduction of the difference to an allowable level within maximum permissible error limits.

Features Calibration can be performed externally or internally.

External calibration can be performed:

– with a factory-defined weight – with a user-defined weight

You can have calibration and adjustment results documented as a ISO/GLP-compliant printout; see the next page.

Selecting the Calibration/Adjustment Mode

Repeatability Test “reproTEST”

Purpose The “reproTEST” function automatically determines the repeatability of results (based on six individual measurements). In this way, the weighing system determines one of the most important quantities.

Definition Repeatability is the ability of the weighing system in the moisture analyzer to display identical readouts when it is loaded several times with the same weight under constant ambient conditions.

The standard deviation for a given number of measurements is used to quantify the repeatability.

Data Input Format

You can connect a computer to your weighing system to send commands via the weighing system interface port to control functions and applications of the weighing system and the drying unit. SBI functions for remote control are only useful, if the current device/application mode can be read out any time.

The commands sent are control commands and may have different formats; e.g., control commands can have up to 26 characters. Each character must be transmitted according to the settings configured in the Setup menu for data transmission.

Format for Control Commands Format 1: Esc ! CR LF Format 2: Esc ! _ CR LF Format 3: Esc ! # _ CR LF Format 4: Esc ! # max. 20 & _ CR LF

Esc: Escape _: Underline (ASCII 95) !: Command character CR: Carriage RETURN (optional) #: 1 or 2 digits LF: Line FEED (optional) &: Digit or letter max. Depends on command character,

i.e. parameter: once the max. length is attained, the input received cut off, rather than being rejected as with a keyboard input.

TEST

Synchronization

During data communication between the moisture analyzer and an on-line device (computer), messages consisting of ASCII characters are transmitted via the interface. For error-free data communication, the parameters for baud rate, parity, handshake mode and character format must be the same for both units.

You can adapt your moisture analyzer by setting corresponding parameters in the Setup menu.

If you do not plug a peripheral device into the analyzer’s interface port, this will not generate an error message.

Handshake

The moisture analyzer interface SBI has transmit and receive buffers. You can define the handshake parameter in the Setup menu:

– Hardware handshake (CTS/DTR)

– Software handshake (XON, XOFF)

Hardware Handshake

With a hardware handshake, 1 more character can be transmitted after CTS (Clear to Send).

Software Handshake

The software handshake is controlled via XON and XOFF. When a device is switched on, XON must be transmitted to enable any connected device to communicate.

When the software handshake is configured in the Setup menu, the hardware handshake becomes active after the software handshake.

The data transmission sequence is as follows:

Moisture ––– byte –––> Computer analyzer ––– byte –––> (receiving (transmitting ––– byte –––> device) device) ––– byte –––>

<––– XOFF –––

––– byte –––> ––– byte –––>

…

(Pause)

… <––– XON ––– ––– byte –––> ––– byte –––> ––– byte –––> ––– byte –––>

Transmitting Device:

Once XOFF has been received, it prevents further transmission of characters. When XON in received, it re-enables the transmitting device to send data.

Receiving Device:

To prevent too many control commands from being received at one time, XON is not transmitted until the buffer is almost empty.

Activating Data Output

You can define the data output parameter so that output is activated either when a print command is received or automatically and synchronously with the analyzer display or at defined intervals (Program: Printout intermediate results: On: Print interval).

Data Output by Print Command

The print command can be transmitted by pressing or by a software command (Esc P).

Digital Input/Output Ports

Monitoring, Remote Control

You can monitor and remote-control the moisture analyzer. For this purpose, you should know the operating state of the unit.

The following external devices can be used here: – Status display with digital input

ports

– Process logic controllers

– Computer with communications

port

Via the communications port, the status of the moisture analyzer and therefore the operating state of analysis can be read out. The moisture analyzer is remote-controlled by the functions used to activate the key functions.

Functions for Remote Control (see also “Data Input Format” and “Data Output Format”):

Read out the moisture analyzer status: ESCars_

Block/unblock the keys on the moisture analyzer: ESCO / ESCR or on the moisture analyzer via Setup: Device

Activate key functions: ESCP, ESCkF1_ to ESCkF11_

The respective operating state of the moisture analyzer will be transmitted to the digital output ports according to the chart “Operating State of Analysis” (see below).

The moisture limits for the control function at the ANALYSIS END (in tolerance, < min., > max.) are to be entered under soft key

Mode: Lim-

its for control function.

Remote control via the universal remote control switch input (pin 15):

● Set the universal remote control

switch function to “Function key F1” (“Setup: Device: Extra functions: Ext. switch”)

$ Block/unblock the keys on the

moisture analyzer, if necessary (“Setup: Device: Keys: Block”)

$ For complete control and analysis

using the F1function key, set the analysis start mode to “Fully automatic, with (without) stability” (Prog.xx: Start analysis)

If a bar code scanner/additional keypad is set, remote control is no longer possible via the universal remote control switch input.
