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

2Maximum cell operation pressure to be 175 psig, based upon standard Sapphire window cell design. Higher pressures available.

3The sample flow through the analyzer should be regulated to within ± 5% of its recommended absolute nominal set point flow value (typically 20-60ccm). This will avoid any pressure drops across any orifices or poor temperature control of the sample.

4The temperature of the sample from the take-off thorough the sample cell must be non-freezing, non- crystallizing, non-coating as provided by customer.

5The sample temperature should not vary at the inlet more than ± 15 OC of the calibration temperature, nor exceed the design operating specifications typically5-45 OC. Assume sample below 45 C and requires no cooling.

6Any background components later found to be present and not specified in the original application feasibility may void the instrument performance should they interfere. particulates assumed none.

7If compounds are found present, such as moisture, acid gases or corrosive solvents, etc., the sample system materials may be compromised for corrosion resistance integrity. We assume that the sample will not polymerize, clog or react in any 1/4" sample line, filter or sample cell when transporting through the sample systems for all inlet ambient or sample pressures and temperatures from takeoff or derived from sample conditioning. Special materials may be required for stability, corrosion protection, coalesc- ing, filtering, hazardous protection or due to heating or cooling.

8We recommend when ambient temperatures exceed outside a 1-50 OC range that the instrument and sample system be conditioned appropriately for heating/ cooling without condensation, crystallizing, coating, polymerization, etc.

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.

10Teledyne is not responsible for applying a general purpose instrument in a hazardous area or where a flammable or toxic gas or liquid is brought to an analyzer above its lower explosive limit and the area has been classified as general purpose and safe.

11The internal calibration features using optical filters are optimized and used when the sample can be flushed (backflushed usually) out of the sample cell using dry nitrogen or air to a reproducible back- ground zero. The zero offset and/or span flag is introduced and set-up to simulate the on-line calibration only after the customer has calibrated the analyzer on the representative process fluid. Thereafter, no calibration fluids are needed to check analyzer.
