Quote "Exceptions" and "GAS PHASE Conditions" for this application:

1Response Time is proportional to sample system design for take-off distance, process pressure, line size, by-pass flow design, dead- volumes/tee's, sample cell volume and instrument electronics.

2We assume no particulates that could plug the lines or contaminate the optical components.

3Control the pressure in the measuring sample cell to within 0.5 % of the nominal operating cell pressure (for example: 760 mm ± 4 mm Hg absolute) is required, return pressure assume to be stable at 1 ATM A. Maximum cell operation pressure to be 5 psig based upon stan- dard metal/sapphire cell design.

4The sample flow through the analyzer should be regulated to within ± 5% of its recommended absolute nominal set point flow value. This will avoid any pressure drops across any orifices.

5The temperature of the sample from the take-off thorough the sample cell must be maintained above its dew point to prevent any moisture or (vapor pressure) for other possible condensables/mists from occurring and affecting instrument performance. (Loss of CO2 or other soluble gases)

6The sample temperature should not vary at the inlet more than ± 15 OC of the calibration temperature, nor exceed the design operating specifi- cations typically 1-50 OC.

7Any background components later found to be present and not speci- fied in the original application feasibility may void the instrument perfor- mance should they interfere.

For CO2 the impurity of N2O will interfere. Assume no others at mea- suring wavelength.

8We recommend when ambient temperatures exceed outside a 5-45OC range that the instrument and sample system be conditioned appropri- ately for heating/ cooling without condensation.

9Should the general purpose or explosion proof instrument be supplied on a back-panel or as a bulk-mount housing, the customer must install to protect the instrument to meet harsh ambient conditions for dust, water, snow, wind, corrosion, etc.
