Emerson has designed the analyzer for industrial process applications requiring ATEX Zone
1 hazardous area certification; the analyzer has an Ex d flameproof enclosure. It contains
an optical system with multiple lasers and a series of optical components that provide an
optical path, a heated multi-pass analysis cell, and sample and outlet ports that can be
connected to a gas handling system, and control and analysis electronics. The number of
lasers installed depends upon customer requirements. The complete system operates Vac
from a 110/240 Vac 50/60 Hz supply.
The analyzer uses mid-infrared optical absorption spectroscopy to measure gas
concentrations. The light sources are lasers, which are operated to produce wavelength
sweeps that cover the absorption lines of the gases. The light from each laser is routed
through an optical path to the analysis cell, which provides measurement of low
concentrations of the subject gases. An external sample handling system conditions the
sample gas and draws it through the analysis cell. The light exits the multi-pass analysis
cell and is directed to a receiver in the analyzer. The variation in the intensity of light in the
vicinity of the absorption lines is measured, and the concentration is determined using a
comprehensive spectral fitting routine.
There is no sample conditioning provided within the analyzer; the sampled gas must be
brought within the parameters shown in
