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

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

• 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

• Calibration Valve Options: Due to there being no N

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

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 ) .

3.4. INITIAL CALIBRATION
3.4.1. CALIBRATION GASES
The information found in the Calibration Gases section of the T300/T300M Operators Manual (P/N 06864) is
applicable to the T320/T320U with the following exceptions:
ZERO GAS
Zero gas is similar in chemical composition to the atmosphere that is to be measured but scrubbed of all
components that might affect the analyzers readings, in this case N
T320/T320U this gas MUST be synthetic air, ultra zero air or nitrogen (N
NOTE
Zero air created by a Zero Air Generator like the T-API Model T701 should not be used since the T701
does not scrub N2O. Likewise since there are no effective and convenient catalytic, absor ptive or
reactive scrubbers for N2O, T-API does not offer a zero scrubber cartridge.

).

SPAN GAS
Span gas is specifically mixed to match the chemical composition of the type of gas being measured at
near full scale of the desired measurement range. In this case, N
T320/T320U analyzer, it is recommended that you use a span gas with a N
80% of the measurement range for your application.
EXAMPLE: If the application is to measure between 0 ppm and 500 ppm, an appropriate span gas
concentration would be 400 ppm N
Some applications require a multipoint calibration procedure where span gases of different
concentrations are applied to the analyzer under test. We recommend using a bottle of calibrated N
gas of higher concentration in conjunction with a gas dilution calibrator such as a Teledyne Instruments
Model T700. This type of calibrator precisely mixes a high concentration gas from with zero gas (both
supplied externally as either synthetic air or N
concentration. Linearity profiles can be automated with this model and run unattended over night.
Currently there are no Standard Reference Material (SRM) N
(National Institute of Standards and Technology) therefore it is essential that span gas be purchased
from a reputable supplier and that the gas be traceable to a reputable national standards laboratory.

3.4.5. PNEUMATIC CONNECTIONS TO T320/T320U IN MULTIPOINT CALIBRATION
Some applications re quir e multipoint calibration checks where Span gas of several different concentrations is
needed. We recommend using high-concentration, certified, calibration gas supplied to the analyzer through a
gas dilution calibrator such as a Teledyne API T700. This type of calibrator precisely mixes span gas and zero
air to produce max concentration levels between 0 ppm and the concentration of the certified gas. This means
that both the source of zero air and span gas must be connected to the calibrator whose output is then
connected to the span inlet on the rear panel of the instrument.

5.1.1. ZERO/SPAN WITH COMMON SHUTOFF VALVES (OPTION 50G)
Option 50G is operationally and pneumatically similar to Option 50B (see T300/T300M manual), except that both
the zero and span gases are applied to the analyzer under pressure. This option is designed to be used with
bottled zero and span gases. A shutoff valve is used to stop flow from the bottles during sample mode and a
common vent is used to bring the pressure of the calibration gas down to local ambient pressure.

NOTE
Upper span limit setting for the individual range modes are shared. Resetting the span limit in one mode
also resets the span limit for the corresponding range in the other modes as follows:
NOTE
Concentrations displayed in mg/m3 and ug/m3 use 0°C , 760 mmHg for Standard Temperature and
Pressure (STP). Consult your local regulations for the STP used by your agency.
NOTE
Once the units of measurement have been changed, the unit MUST be recalibrated, as the “expected
span values” previously in effect will no longer be valid. Simply entering new expected span values
without running the entire calibration routine is not sufficient.
The following equations give approximate conversions between volume/volume units and
weight/volume units:
N2O ppb x 2.052 = N2O ug/m

N2O ppm x 2.052 = N2O mg/m3

9. CALIBRATION P ROCEDURES
Calibration of the T320/T320U should be perf ormed according to the procedures des c ribed in the Calibration
esction of the T300/T300M Manual - P/N 06864 with the following notes and exceptions:
• Delivering span and zero gases for the higher resolution the T320/T320U can be difficult. Attention must
be paid to the quality of the gases, the level of contaminants in the gases as well as the history and
conditioning of the gas delivery components.
• The analyzer must be continually operating with and adequate flow of sample gas, for 2 hours prior to
performing a calibration (12 hours is recommended for the initial calibration).
• DO NOT calibrate the analyzer if it has been turned off or if no sample gas has been flow though it
within the last 2 hours.
• After this stabilization period is complete and just prior to performing the initial calibration, force the
instrument to perform an auto-reference measurement.
REQUIRED EQUIPMENT, SUPPLIES AND EXPEND ABL ES
• Gas lines to and from the analyzer should be PTFE or FEP Teflon, glass, or stainless steel only.
• Zero-air source which must be synthetic air, ultra-zero air or nitrogen (N
). A zero air generator like a T-
2
API M701 should not be used.
• Span gas source (defined in the Calibration section’s Span Gas subsection of the T300/T300M
Operators Manual; but use N
O instead of CO).
2
• A recording device such as a strip-chart recorder and/or data logger (optional). Data recording device
should be capable of bi-polar operation so that negative readings can be recorded.
• For electronic documentation, the internal data acquisition system can be used.
NOTE
If any problems occur while performing the fo llowing calibration procedures, refer to Troubleshooting
and Service sectionthe T300/T300M manual for troubleshooting tips.
MANUAL CAL IBRATION
The information found in the Manual Calibration section of the T300/T300M Operators Manual (P/N 06864) is
applicable to the T320/T320U with the following exception:
• Set the display to show the N2OSTB test rather than the CO STB test function mentioned in the
T300/T300M operator’s manual.
