1.2 Anatel® PAT700 analyzer overview
The Anatel® PAT700 analyzer provides TOC analysis for pure and ultra-pure water
processing. The PAT700 oxidizes a water sample to determine the TOC in the sample. The
analyzer traps a sample in the analysis cell, exposes the samp le to ultraviole t (UV) light, and
monitors changes in temperature and conductivity until the sample has completely oxidized.
Once full oxidation has occurred, the analyzer reports TOC, temperature, conductivity, the
oxidation curve type, and TOC trend. The PAT700 incorporates the OASIS™ onboard,
automated standards introduction system that simplifies analyzer performance testing using
standards bottles tagged with RFID technology.

A touch-screen interface provides access to all analyzer functions. The user interface consists
of a home screen from which all user operations initiate. The home screen displays the
current status of the analyzer and analysis results based on the current run mode selection.
The software can display data in a number of user-selected formats, including TOC,
compensated and uncompensated conductivity, resistivity, and temperature in engineering

1.3 RFID technology
The Anatel PAT700 on-line TOC analyzer Onboard Automated Standards Introduction
System (OASIS™) employs Radio Frequency Identification (RFID) technology, a registered
radio frequency device. The RFID system in the PAT700 operates over a very short distance
to eliminate any interference with other wireless communications.
The term RFID describes a system that transmits data wirelessly using radio waves. An RFID
system is comprised of a “tag” and a “reader/writer”. In the PAT700 analyzer, the tag is
attached to the standards bottles used in calibrations (conductivity and TOC), validations,
system suitability tests, and excursion mode. The RFID tag consists of a microchip attached
to a radio antenna mounted on a substrate. The RFID tag is attached to the bottom of the
standards bottle. The microchip contains data about the standard contained in the bottle. The
PAT700 OASIS system contains four RFID reader/writers permanently mounted inside the
analyzer that align with the bottle RFID tags when the bottles are fully loaded in the analyzer.
Operator Manual Anatel
WGM - 28 November 2007 - Edition 01
P AT700 To tal Organic Carbon Analyzer – Before You Begin Page 3
The reader/writer retrieves the data stored on the RFID tags located on the bottom of the
standards bottles. The RFID reader/writers have antennas that emit radio waves and receive
signals back from the tags on the standards bottles. The information provided from the tag
includes the identity of the standard, the standard’s concentration, date of expiration and other
pertinent data.
The reader/writer takes the data received from the tag and passes the information in digital
form to the PAT700 processor. The RFID system in the PAT700 can read and write to the
RFID tags attached to the standards bottle. The writing feature allows the PAT700 to write
data to the bottles showing that the bottle has been used and provides for writing of data for
the exclusive excursion sampling feature.
The RFID system in the PAT700 does not require any user intervention to operate. The
system operates automatically when bottle tests are performed. The system automatically
turns on and off to read and write data only when necessary. When enabled, the radio
frequency modulation emitted from the antennas is fixed at 13.56 Mhz. There are no user
serviceable parts associated with the RFID system. The RFID reader/writer board assembly
should only be serviced by a Hach Ultra certified service representative.
Since the RFID labels on the standards bottles contain the data necessary for each standard,
the labels must not be removed from the bottle. Without the label, the RFID reader/writer has
no data to read and will not operate as intended; however, bottles without labels can b e run if
the user manually enters data.

1.12 Definitions of terms
The following terms are used throughout this manual:
Conductivity. A measure of the ability to conduct current through water. Conductivity, very
low with high-purity deionized water, is the reciprocal of resistivity and is measured in
microsiemens per centimeter (μS/cm).
Megohm (M). A measurement of 1,000,000 ohms.
Microsiemens (μS). A unit of conductance in the metric system equivalent to one millionth of
an ampere per volt (1 µS = 1 x 10
Normalize. To make conform to a standard. In this case, the user performs calculations on
the raw data to produce a result in a standard unit of measure.
Organic. A molecule that contains carbon but excludes carbonate CO
related compounds. Oxygen is very common in organics, and they almost always include

Parts per billion (ppb). A term used to report trace chemical analyses. It refers to the
concentration of the element or compound present within one billion parts of water. One
microgram per liter (µg/L) is equal to 1 ppb).
Resistivity. Resistance, measured in megohmcentimeters (MΩ-cm), to the flow of electrical
current through high-purity water. Resistivity is a means of continuously measuring the
purity of the water and is the reciprocal of conductivity.
Temperature compensation. Conductivity and resistivity measurements normalized to
25 °C (77 °F) for reporting purposes. Normalized conductivity and resistivity
measurements reflect the values that would be reported at a sample temperature of 25 °C
(77 °F) using a model based on sodium chloride in water. Conductivity and resistivity of
electric current in water depend on the temperature of the water. The lower the
temperature, the lower the conductivity and the higher the resistivity.
Total organic carbon (TOC). A measurement of the organics present in water based on its
carbon content. In high-purity water, TOC is measured in parts per billion (ppb). Total
organic carbon is used interchangeably with total oxidizable carbon.

I/O wiring
The analyzer has three 4-20 mA outputs, two discrete inputs, and four discrete outputs.
4-20 mA outputs
The analyzer has three 4-20 mA outputs, as listed in Table 2-7.
• Analog output 1 represents TOC (total organic carbon).
• Analog output 2 represents conductivity or resistivity (user selected).
• Analog output 3 represents temperature in °F or °C (user selected).

Discrete inputs
The analyzer has two discrete inputs, as listed in Table 2-8.
• Discrete input 1 initiates TOC analysis. When the output state switches from high to
low, the ana lyzer stops the cu rrent operation and runs a single T O C analysis. Aft er the
analysis is complete, the analyzer returns to the mode defined by digital in put 2. During
the TOC analysis, the analyzer ignores all subsequent trigger values.
• Discrete input 2 switches the analyzer modes. If digital output 2 is in high state, the
analyzer is in TOC mode. If digit al output 2 is in lo w state, the analyzer runs in flow with
conductivity mode.

Discrete outputs
The analyzer has four discrete outputs, as listed in Table 2-9 and Table 2-10.
• Discrete output 1 is a TOC alarm. The output reports the TOC level as above (low
state) or below (high state) the user-specified alarm limit.
• Discrete output 2 is an uncompensated conductivity alarm. A low state indicates the
conductivity level is above the alarm limit. A high state indicates the conductivity level
is below the alarm limit.
• Discrete output 3 reports a warning or failure condition. A low state indicates an error
condition exists. A high state indicates no error conditions exist.
• Discrete output 4 reports a TOC analysis start (by indicating the state of the sample
inlet valve). A low state indicates the sample valve is closed. A high state indicates the
sample valve is open.

2.7 RS-232 commands
Commands consist of 2-character, ASCII text mnemonics. Some commands require one or
more arguments, each delimited by at least one space (ASCII 32, 20
command mnemonic. Each command string is terminated by a carriage return (ASCII 13,
0D
).
Hex
The analyzer responds to commands with an “OK>” prompt after the command has been
processed. Data read and parameter read commands elicit a reply consisting of o ne or more
numeric or text values delimited by at least one space and terminated by a carriage return,
linefeed pair – “\r\n” (ASCII 13, 10; 0D, 0A
). Commands and replies use a free field format,
Hex
in which the number of delimiting spaces and length of each argument or data field vary. If a
command is rejected (for example, due to invalid syntax), the “OK>” prompt followed by a
question mark (ASCII 63, 3F
) reply indicates the rejection.
Hex
Normally, the analyzer transmits only in response to a specific command. For unattended
data collection, you can issue the “SA” command to make the analyzer transmit results.
You can combine multiple commands on a single line by separating them with a semicolon.
The repeat command (an exclamation point followed by a repetition count, such as "!10")
causes the previous valid command line to repeat for the specified number of times.
• To read current values for a parameter set command, enter the command without
arguments.
• Every command must have a suffix with a carriage return.
• Send a carriage return without any command to see the "OK>" prompt.
), following the
Hex
Conventions
• f = Floating point number (such as 1.23, 1.23e3, –1.23, etc.)
• u = Unsigned integer from 0 to 65535
• s = ASCII text string
• YYYY mm DD = 4-digit year, month (where 1 = January and 12 = December), day of
month (1 to 31)
• HH MM SS = Hours, minutes, seconds
• Any command that replies with temperature is in °C.
Setup
The PAT700 communicates at 9600 baud with no parity, 8 data bits, 1 stop bit. The analyzer
supports full-duplex communication without hardware or software handshaking. The “BD”
command can be used for temporarily increasing the baud rate to 115200 baud to reduce the
time required for downloading the data log.
• “BDu” = Set baud rate, Where u: 0 = 9600 baud or 1 = 115200 baud
• “BD” = Get baud rate, returns 0 = 9600 baud or 1 = 115200 baud

Data read commands
“RD”
Read data
Read-only command produces last data. The format depends
on the current mode.
The data normally are displayed only in response to the “RD” command. If the “SA” command
is sent, data will be displayed at the end of each measurement. After the analyzer powers up,
it initially responds with zeros in all data fields until the first valid reading is taken. For TOC
data, the timestamp represents the time at which the unit finished sampling and began
oxidation.
The data format can take either of two forms, depending on whether the sensor is in TOC
mode or conductivity mode.
The analyzer produces new data every 15 seconds in conductivity mode or from 1 to 35
minutes in TOC mode. If the “RD command is used for polling, you can distinguish a new
reading by comparing the current timestamp with the previous timestamp.
Example:
Read command: “RD”
TOC mode response:
“Date Time Mode State TOC alarm Percentage Trend

Chapter 3 Startup
3.1 Startup sequence
The analyzer goes through the following sequence on power up:
1) Splash window: The splash window appears at startup while the system launches
the application.
2) Verify lamp monitor: After the system has initialized, it verifies that the lamp
monitor works by turning on the main lamp and ensuring a voltage is returned.
3) Sample bottle check: The system checks to see if the bottles loaded in the bottle
bay match the last known configuration. If the bottles contain RFID tags, the
analyzer reads the tags and compares them against the information stored in the
settings. If the RFID tag doesn’t match what’s stored in the settings, the settin gs are
updated with the new information and a warning is generated. If the settings list a
non-RFID tagged bottle in one of the bottle positions and an RFID tag cannot be
detected in that position, the analyzer assumes the bottle is still present.
4) Start sampling: If the analyzer is configured for online TOC, it starts sampling after
it has powered up.
5) Print header: After the system has started up, it prints a daily header.
3.2 Logging on and off
The sign on and sign off icons enable you to sign on or sign off the analyzer. By default,
security is disabled and the user cannot sign on. To enable security, see Security, page 59.

Chapter 4 Run Modes
4.1 The analysis cycle
An analysis cycle is comprised of a flush of the analysis cell, oxidation, and idle time (if the
cycle time is greater than the combined flush and oxidation time).
Oxidation time varies based on the amount of total organic carbon in the sample. Flush time
is configurable and idle time varies to allow for varying analysis cycle time. See Figure 4-1.
Idle time occurs only after an online TOC analysis has been completed and only if the elapsed
time has not exceeded the value for cycle time.
During idle time, the analyzer can operate in one of three ways: flow without conductivity, flow
with conductivity, or no flow.
• When flow without conductivity is selected, the sample valve opens during idle,
allowing continuous flow through the cell. No conductivity is reported.
• When flow with conductivity is selected, the sample valve opens during idle, allowing
continuous flow through the cell. Conductivity of the water is reported.
• When no-flow is selected, the analyzer sample valve closes, stopping all flow through
the sample cell during idle.

Sampling with pressure
CAUTION
Potential burst hazard! Do not exceed the maximum 100 psi (6 90k Pa) sample pressure
ratings.
NOTE
Using the sample pump on a pressurized system could damage the pump. Do not use
the sample pump on a pressurized system.
In online TOC mode, the cell valve opens to flush the cell.
• When flushing is completed, the cell’s sample valve closes, the analysis begins, and
initial conductivity and temperature readings are fed into the TOC algorithm.
Conductivity is monitored until oxidation is complete.
• When oxidation is complete, the analyzer reports the results to the home screen, the
data log, and the printer, based on the printer settings and if the printer is connected.
The analyzer then checks to see if the elapsed time is greater than or equal to the
value for cycle time in settings. If it is, the next online TOC analysis is started.
Otherwise, the analyzer enters the idle mode.
Sampling from a zero pressure system
If you are sampling from a zero pressure system, you can enable the pump option to draw
water into the cell. For instructions on setting up the pump option, see TOC, General tab,
page 48.
4.4 Conductivity mode
In conductivity mode, the home screen displays conductivity and temperature readings. See
Figure 4-4.

Anatel Operator Manual
Page 44 Run Modes – PAT700 Total Organic Carbon Analyzer
In conductivity mode, the analyzer starts by verifying that the UV lamp is off and the cell valve
is open to flush the cell. The analyzer reports the current readings for conductivity and
temperature every time a new value is available. The reported value is an ave rage of the data
over the last two seconds. The average reading is also sent to the printer, based on the
printout settings, and to the data log. One data point is written to the log every 60 seconds.
4.5 Standby mode
In standby mode, the analyzer verifies that the lamp is off and the valves are open. The
valves, lamp, and pump states are based on the flow during idle setting. (See Idle tab,
page 49.) You can terminate standby mode by switching to another mode.
4.6 Offline mode
In offline mode, the analyzer verifies that the lamp is off, the valves are closed, and flow
through the analyzer has stopped. You can terminate offline mode by switching to another
mode.

Chapter 6 Bottle Mode
6.1 Calibration and validation
Bottle mode allows you to perform calibration, validation, and system suitability test
procedures on the PAT700. Proper calibration of the analyzer is critical to maintaining
optimum instrument performance. You may perform such functions automatically with the
Onboard Automated Standards Introduction System (OASIS™) using the touch-screen
interface. This method minimizes user intervention by using a prepackage d standards kit with
RFID technology. You may run calibration, validation, and system suitability test procedures
immediately or schedule them to run later.
This chapter provides general instructions on performing calibration and validation
procedures. Refer to the specific Standard Operating Procedure (SOP) for detailed
instructions.
• Calibration assures the accuracy of instrument’s readings at regular intervals.The
PAT700 is calibrated at the factory before shipment. You do not need to perform a
TOC calibration before placing the analyzer into service.
• Validation ensures the accuracy of the calibration by challenging the calibration with
the analysis of a known standard.
• Calibration and validation involve running analyses of one or more standards and
blanks (protocols) to determine analyzer response.
• In bottle mode, the analog output retains the last online TOC, conductivity, and
temperature values, and TOC and conductivity alarms are deactivated.
Four functions are available under bottle mode: run standards, grab sample, excursion mode ,
and unload bottles.
Onboard Automated Standards Introduction System (OASIS)
The PAT700 Onboard Automated Standards Introduction System (OASIS) is used for
performing standards tests, grab sampling, and excursion sampling. Through the bottle mode,
various bottle test functions can be selected. The OASIS system is automated through the
use of RFID technology (see RFID technology, page 2). When standards bottles with RFID
tags are installed in the system, the analyzer uses RFID technology to read and transmit data
about the standards to the analyzer. This system eliminates the need for manual data entry.
Although equipped to perform automatically using RFID tagged standards, you may also use
bottles without RFID tags by manually entering the standards data when prompted by the
analyzer.
TOC calibration protocol
Select up to three levels (250, 500 and 750 ppb) of a sucrose standard. For maximum
accuracy, the procedure allows up to three analysis replicates per standard.
TOC validation protocol
Perform a single-point or multi-point validation of the TOC calibration using up to three levels
WGM - 28 November 2007 - Edition 01
of sucrose validation standards.
Anatel Operator Manual
Page 76 Bottle Mode – PAT700 Total Organic Carbon Analyzer
Conductivity calibration protocol
Perform a conductivity calibration according to the guidelines established in USP Method
<645>. The procedure uses an NIST-traceable calibrated resistor for determining meter
accuracy and an NIST-traceable 100 μS/cm conductivity standard for cell constant
verification.
System suitability protocol
Perform a system suitability test according to the guidelines established in USP Method
<643> using prepackaged 500 ppb sucrose and 500 ppb 1,4-benzoquinone standards.
6.2 Accessing bottle mode

6.5 TOC calibration
TOC calibration ensures the accuracy of the TOC values obtained by the analyzer. TOC
values are determined by measuring the change in conductivity of a high-pu rity water sample
as its organic compounds oxidize to carbon dioxide inside the analysis cell. The procedure
subtracts the average of a series of background TOC measurements from the average of a
series of user-selected standard measurements (in the form of sucrose). Linear regr ession is
performed on the data, and the correlation coefficient (R
are calculated and reported.

6.6 Conductivity calibration
CAUTION
Potential puncture hazard! Contact with the exposed needle could cause serious
injury. Use extreme care when installing and removing the sample bottles.
Conductivity calibration ensures the accuracy of the conductivity values reported by the
PAT700 TOC analyzer. A conductivity calibration consists of verifying the conductivity meter
using a precision resistor. The cell constant is adjusted to the value of the conductivity
standard, and therefore is always within ±2%. If the new calibration is greater than ±10% of
the factory calibration or ±5% of the previous user calibration, the calibration is unacceptable
and a new calibration is required.
1) Allow the conductivity calibration standard to warm to room temperature.
2) At the home screen, touch the << icon to open the sliding toolbar.

Verification resistor
14) If the selection has been made to use the conductivity meter verification resistor,
install the resistor onto the analyzer’s 9-pin printer/calibration port, as illustrated in
Figure 6-14.
• If the calibration is being performed on a schedule, the conductivity meter test
dialog box does not appear, and the calibration occurs automatically.
• Otherwise, the conductivity meter test dialog box appears when the analyzer
passes the conductivity meter test. See Figure 6-15.

• Start test icon reads the value of the resistor. The analyzer then converts this
value to conductivity by taking the inverse of the resist ance and multiplying it by the
cell constant. This value is then compared to the expected value, assuming a 61.9
Kohm resistor. If the measured value is less than or equal to ±0.1 µS/cm of the
expected value, the test passes and the forward icon is enabled. Otherwise, you are
notified and must cancel the calibration.
• Cancel icon takes you to a dialog box that notifies you that the test has been
cancelled. The next button on the cancellation dialog box takes you to the unload/
replace bottles dialog box. All changes made in any of the dialog boxes are lost.
15) When the test running dialog box appears, the analyzer begins running the test.
• After verifying the presence of the calibration standard, the analyzer performs a
temperature stabilization. After the temperature has stabilized, the calibration
standard is analyzed.
• The dialog box displays the current status of the test and lists the results of each
repetition and the calibration standards bottle as it is running.
16) When the calibration is completed, the test summary dialog box appears, with the
results of the calibration and a notification of whether the calibration failed or
passed. The results also appear on the printout if a printer is attached. See
Figure 6-16.
17) If the calibration fails, you may run the test again.
Figure 6-16 Test summary dialog box
• Summary text lists the results of the calibration. The results appear as they would
appear on the printed report.
• Export icon takes you to the export dialog box, where you can save the results of
the calibration to a USB flash drive.
• Checkmark icon accepts the calibration, if the values passed, and t akes you to the
unload/replace bottles dialog box.
• Cancel icon rejects the calibration results and t akes you to a dialog bo x that asks if
you want to rerun the test. If you wish to rerun the test, the analyzer returns you to
the beginning of the test. All previous data are discarded.

6.7 TOC validation
CAUTION
Potential puncture hazard! Contact with the exposed needle could cause serious
injury. Use extreme care when installing and removing the sample bottles.
The principles and procedures for performing a TOC validation are essentially the same as
those used for performing a calibration. Validation of the TOC calibration is accomplished by
analyzing user-selected concentrations of sucrose validation standards. You can perform a
validation using a single-point analysis or multi-point analysis. The instrument response for
the validation standard must have a deviation of less than 15% of the calibrated response to
be acceptable.
1) Allow the TOC validation standards to warm to room temperature.
2) At the home screen, touch the << icon to open the sliding toolbar, then touch the
bottles icon in the toolbar, or touch the bottles icon in the lower left corner of the
screen.
3) Touch the run standards button in the bottle mode dialog box. See Figure 6-1,
page 76.
4) Touch the TOC validation button in the run standards dialog box. See Figure 6-2,
page 77.
5) To use default settings, touch the use default settings radio button in the TOC
calibration setup dialog box. To run any other configuration, touch the use custom
settings radio button, then define the desired configuration. (See Figure 6-4,
page 79.) The following procedure relies on the recommended default setting.
6) Touch the forward icon. The OASIS door will unlock for five seconds. If the door is
not opened within five seconds, the unlock icon can be used to unlock the door
manually.
7) Install the standards bottles following the instructions as shown in the load bottles
dialog box and ensuring that you place the standards bottles in the correct
positions. See Figure 6-17. The default setting is a blank bottle and one standard of
500 ppb sucrose. You may perform multipoint validation by selecting the custom
settings and defining the desired configuration. From left:
• Bottle 1 = blank
• Bottle 2 = empty
• Bottle 3 = 500 ppb sucrose
• Bottle 4 = empty

• Bottle positions graphics show you the order in which to install the bottles.
• Unlock icon energizes the bottle bay door lock for five seconds, allowing you to
open the door.
• Back icon takes you to the previous dialog box.
• Forward icon takes you to the review test options dialog box.
• Cancel icon returns you to the run standards dialog box. All changes made in any
of the dialog boxes are lost.
8) Close the bottle bay door.
9) T ouch the forward icon. If bottles have been properly loaded and the RFID t ags can
be read, the review test setup dialog box appears. See Figure 6-6, page 81.
Otherwise, the enter bottle information dialog box appears. See Figure 6-7,
page 81.
10) When the test running dialog box appears, the analyzer begins running the test.
• After verifying the presence of the appropriate standards, the analyzer performs a
temperature stabilization. Once the temperature has stabilized, the blank and
standards bottles are analyzed in the proper sequence.
• Once all the bottles have been analyzed, the analyzer compares the current re sults
to the standard calibration. If the average of each standard is within ±15% of the
expected value, the validation is accepted. If any of the averaged values are greater
than ±15% of the expected value, the validation is rejected.
• The dialog box displays the current status of the test and lists the results of each
repetition and bottle as it is running.
11) When the validation is completed, the test summary dialog box appears, with the
results of the validation and a notification of whether the validation failed or passed.
The results also appear on the printout if a printer is attached. See Figure 6-10,
page 83. Touching the forward icon takes you to the run again dialog box
(Figure 6-12, page 85). If the test failed or you have rejected the calibration results,
at the run again dialog box, touch the checkmark icon to run the validation again or
the cancel icon to cancel the run.
