2.1. Description The Model 100 single component, the Model 200 dual component, and the Model 300 three component infrared analyzers all incorporate a single-beam photometric system and a detector with a microflow sensor assuring high reliability, sensitivity, accuracy and stability. Depending upon the configuration, the analyzer may have one, two, or three optical benches within one case.
Section 2 Models 100, 200, 300 Infrared Analyzers The infrared light energy is partially absorbed in the front chamber and residual light is absorbed in the rear chamber, thereby increasing pressure in both chambers. Since the detector is designed to produce a pressure difference between the front and rear chambers, a slight gas flow is produced through a path connecting these chambers with each other.
Section 2 Models 100, 200, 300 Infrared Analyzers 2.4. Interference Gases Whenever a sample gas contains a gas component that has an absorption spectrum that overlaps the spectrum of the gas to be measured, that gas is commonly referred to as an interference gas.
The operation of the analyzer is based upon the principle of the magneto-dynamic oxygen cell, the most accurate and reliable cell for determining the oxygen content of a gas mixture from 0-100 percent volume oxygen.
Section 2 Models 100, 200, 300 Infrared Analyzers 2.6.2. Galvanic Fuel Cell Oxygen Option This analyzer option utilizes a low cost fuel cell to determine the percent level of oxygen contained in the sample gas. The oxygen level is displayed on a digital panel meter.
