Or, if desired, one set of linearizing coefficients may be used for all three ranges when the dynamic range ratio is 3:1 or less. If only one set of coefficients is used, this set should always be entered in Range 3.

3.18 INTERFERENCE BALANCE Measurement The Model 890 analyzer may be calibrated for a dynamic interferent gas rejection ratio of up to 1000:1 for samples containing single, binary or multiple interferents. This calibration is initially done at the factory, and generally is a one-time adjustment.
This increase yields an extremely stable, sensitive and drift- free analysis. The Model 890 employs a pulsed UV lamp with peak wavelength generation from 225 to 650 nanometers. The pulsed lamp eliminates the requirement for a mechanical chopper and the attendant noise and stability problems.
