Introduction
The gas analyzer operates by comparing the infrared transmission of two spectral bands through one
optical path. One spectral band is centered in one of the absorption bands of the gas being measured. The
other spectral band is of a reference wavelength in which there is no absorption by any of the gases
present in the sample stream. The difference in the transmittance of these two signals through the optical
path is a measure of the optical absorption of the gas being measured in the sample stream as sensed by
the infrared detector. The signal from the detector is electronically processed and used to derive a direct
measurement of the measured gas concentration in the sample gas.

The Infrared Industries 8400D series models are non-dispersive infrared (NDIR) gas analyzers, capable
of continuously monitoring various gases in a sample stream for extended periods of time. The IR-8400D
is designed specifically for the measurement of Hydrocarbons, Carbon Dioxide, Carbon Monoxide,
Oxygen, and Oxides of Nitrogen. Other non-standard gases are possible. Contact your IRI representative
for further details. The ranges for the IR-8400D are specified by the end users requirements. The
instrument is designed specifically for enhanced oil recovery applications as well as refineries and
petroleum transfer station. The analyzers are temperature and pressure compensated to achieve
