700 LX Series CLD Analyzer utilizes the principle of chemiluminescence for analyzing the NO or NOx concentration within a gaseous sample. In the NO mode, the method is based upon the chemiluminescent reaction between ozone and nitric oxide (NO) yielding nitrogen dioxide (N02) and oxygen. This reaction produces light which has intensity proportional to the mass flow rate of N02 into the reaction chamber. The light is measured by means of a photodiode and associated amplification electronics. In the NOx mode, NO plus N02 is determined as above, however, the sample is first routed through the internal N02 to NO converter which converts the N02 in the sample to NO. The resultant reaction is directly proportional to the total concentration of NOx.

The California Analytical 700 LX Series CLD/O2 Analyzer utilizes the principle of chemiluminescence for analyzing the NO or NOx concentration within a gaseous sample. In the NO mode, the method is based upon the chemiluminescent reaction between ozone and nitric oxide (NO) yielding nitrogen dioxide (NO2) and oxygen. This reaction produces light which has intensity proportional to the mass flow rate of NO2 into the reaction chamber. The light is measured by means of a photodiode and associated amplification electronics. In the NOx mode, NO plus NO21S determined as above, however, the sample is first routed through the Internal N02 to NO converter which converts the NO2 in the sample to NO. The resultant reaction is directly proportional to the total concentration of NOx. 0-25% oxygen is measured by the paramagnetic method

The 600SC Series FTIR Analyzer delivers fast, accurate analysis of virtually any gas that has an infrared absorption spectrum. The 600SC Series FTIR is based on Fourier Transform Infra-red Spectroscopy. Nonsymmetrical gas phase molecules absorb IR light which in turn causes the molecular bonds to stretch, bend, or rotate. This absorption is used to measure and quantify several chemical components simultaneously. An IR source emits radiation in the range of 7500 to 375 crrr1. The IR radiation is split in a Michelson nterferometer where half of the light passes through to a fixed mirror and the other half is reflected towards a moving mirror.

The California Analytical Instruments` 700 LX Series NDIR analyzer is based on the infrared absorption characteristics of gases. Using a single infrared beam to measure gas concentrations, this analyzer produces highly stable and reliable results. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some of its energy. The oxygen analyzer section utilizes either the paramagnetic or fuel cell method to determine the level of oxygen in the sample gas

The ZPA analyzer uses NDIR technology to measure CO, C02, CH4, S02, NO and paramagnetic or fuel cell for oxygen. The ZPA NDIR technology is based on the infrared absorption characteristics of gases. Using a single infrared beam to measure gas concentrations, this analyzer produces highly stable and reliable results. A single infrared light beam is modulated by a chopper system and passed through a sample cell of predetermined length containing the gas sample to be analyzed. As the beam passes through the cell, the sample gas absorbs some of its energy. The attenuated beam (transmittance) emerges from the cell and is introduced to the front chamber of a two-chamber infrared microflow detector.

CAI offers two dedicated analyzer options to measure oxygen. Either paramagnetic technology or the fuel cell method may be used to determine the percentage level of oxygen in the gas sample.
