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 sample to ultraviolet (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, and the oxidation curve. 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 operation initiates. The home screen displays the current status of the analyzer, TOC level, and environmental data. The software can display data in a number of user-selected formats, including TOC, compensated and uncompensa ted conductivity, and temperature in engineering units, with graphical representations of the data. Compliance with 21 CFR Part 11 is ensured with password protection and an audit trail of all

• You can interact with the analyzer remotely, including downloading data records, by querying the analyzer through an RS-232 communications port.

• You can communicate with the analyzer using Modbus

protocol via the Ethernet port. Alternatively, the user may connect a memory stick to the unit and download the contents of the data buffer and bottle analysis reports.

• You can print data on a remote printer via the RS-232 serial port.

• Printing may be done automatically or on demand through an RS-232 port to a serial printer.

1.3 RFID technology

The Aantel 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, over a very short distance. 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, and system suitability tests. 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. 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.

Operator Manual Anatel

WGM - 26 July 2007 - Edition 01-d4

PAT700 Total Organic Carbon Analyzer – Before You Begin Page 3

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.

1.8 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

-6

an ampere per volt (1 µS = 1 x 10

A/V).

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. Organic chemicals, including carbon atoms in complex molecules, but not including

carbonate (CO

, HCO3, CO3) or cyanide (CN) related compounds. Oxygen is very common

in organics, and they almost always include hydrogen.

Oxidation. The loss of electrons by a chemical species, typically with oxygen. Organic

carbon, for example, oxidizes to carbon dioxide and water.

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 (M-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.

Mounting general considerations

Follow these guidelines when installing the analyzer:

• Locate the analyzer where it is accessible for operation, service and calibration.

• Minimize the distance between the water system sample point and the analyzer to allow for representative sampling.

• Locate the analyzer where the ambient temperature remains between 15 and 35 °C (59 and 95 °F).

• The transmitter mounting bracket is installed independently from the analyzer. Once mounted, the analyzer hooks on the mounting bracket and locks into place with twist latches.

• Mount the transmitter mounting bracket to a stable, flat surface or dual instrument poles.

• The front of the analyzer requires 12 inches (30.48 cm) of clearance to allow the doors to open completely.

• The analyzer is available with ¾-inch conduit openings or quick-connect fittings for power and I/O wiring. If conduit is used, install fittings that ensure a complete seal with the openings and are properly sealed to keep the analyzer electronics compartment watertight.

Mounting to a wall

Follow these guidelines and refer to Figure 2-1 and Figure 2-3 to mount the transmitter to a wall or other flat, rigid surface:

• Use 5/16-inch (8 mm) diameter screws or bolts and nuts to mount the analyzer to a wall or other flat, rigid surface. Use hardware that can withstand the process environment. Hach Ultra does not supply hardware.

• To minimize stress on the analyzer mounting bracket, secure all mounting bolts to the same structure, which should be flat and should not vibrate or move excessively. Do not secure bolts to separate girders, beams, or wall studs, which can move independently.
