1. INTRODUCTION

The T320 and T320U are Gas Filter Correlation (GFC) analyzers that are designed to measure low level and
trace level nitrous oxide (N
operating range; 1000 ppm for the T320 and 200 ppm for the T320U. The T320 and T320U are designed to be
used for monitoring background levels of N
contamination of bottled gases.

This addendum is a supplement to the T300/T300M manual (P/N 06864) to facilitate setup, operation,
calibration, troubleshooting and repair of T320 and T320U nitrous oxide (N
up information, operating ins tr uctions as well as maintenance, troubleshooting and repair methods are the same
for the T320/T320U and can be found in the T300/T300M manual (P/N 06864). The T320 is very similar to the
T300M, and the T320U is very similar to the T300:

When using the T300/T300M manual, it is necessary to substitute the words nitrous oxide for carbon monoxide
and the chemical abbreviation N

O), respectively. The primary difference between the models is their maximum

There are six major differences between the T320/T320U and their counterpart models, T300M/T300:

• Operating wavelength: A different photo detector is used that closely matches the peak absorption
wavelength of N

• Gas Filter Correlation Filter (GFC) wheel: The GFC wheel is filled with N

• Software: Display text strings, variable names and variable values reflect the difference in gas name
and physical characteristic. Wherever “CO” is displayed on the T300/T300M “N2O” will be displayed on
the T320/T320U.

• Calibration Methods: There are no specialized USEPA calibration methods since these methods
currently do not exist.

• Calibration Gases: Since there are no readily available low cost N
generators like the TAPI model 701, whic h do not remove N

O, zero gas must be either N2 or synthetic

air - especially for the T320U.

• Calibration Valve Options: Due to there being no N

O scrubbers or traditional zero air generators for

either the T320 or the T320U, Options 51B and 51C for the T300M and T300 are not available for the
T320 or T320U.

NOTE

The information contained in this addendum is relevant to T320/T320U analyzers, some of which may

not be applicable to the current version of software.

2.2. EPA EQUIVALENCY DESIGNATION

There is no US EPA reference method for the measurement of nitrous oxide; therefore, neither the T320 nor the
T320U are designated as reference or equivalent methods. Hence, the EPA Protocol Calibration section of the
Model T300/T300M Operation Manual does not appl y.

See the CE Mark Compliance section of the T300/T300M manual (P/N 06864).

3. GETTING STARTED

3.1. UNPACKING THE T320/T320U

Follow the unpacking directions in the Getting Started section of the T300/T300M manual (P/N 06864); note that
the Final Test and Validation Data Sheet for the T320 or the T320U are unique .

3.2. INITIAL OPERATION OF THE T320/T320U

The analyzer should be started and allowed to warm up; a functional check followed by calibration should be
performed. The process for starting and warming up the T320/T320U is identical to that described in the Initial
Operation section of the T300/T300M Operators Manual (P/N 06864).

3.3. FUNCTIONAL CHECK

The functional check information also in the Initial Operation section of the T300/T300M Operators Manual (P/N

06864) is applicable to the T320/T320U with the following exc epti on(s ) .
