Laser Gas Analyzer & Controller
ARI's Laser Gas Analyzer (LGA) is a unique high-speed gas
spectrometer that measures concentrations of eight or more gases
simultaneously. It includes a completely integrated computer
controller and sampling system that rapidly monitors industrial gas
process operations.
The LGA becomes a complete gas process control system when
connected to manufacturing equipment through appropriate hardware
and software connections. The laser in the LGA detector module
stimulates the gases sampled to emit distinctive light spectra, a
phenomenon called "Raman scattering," named after the scientist who
discovered it. The module has an unlimited gas concentration
detection range from 50 parts-per-million—or lower—to 100% and can
be easily modified to detect gas species of interest to many
industries.
Raman laser effects have been used industrially for the chemical
analysis of solids and liquids; the patented ARI Laser Gas Analyzer
is the only commercial instrument to analyze gases this way. The LGA
System is the only gas analyzer on the market that combines
high-speed gas analysis of so many species at such a low price. The
standard model has the capability of analyzing the eight gas species
important to most heat treating operations.
Automated analysis of complex atmospheres
Changes in gas composition can be detected in as little as 50
milliseconds and the standard analyzer can detect any combination of
eight gas species. Additional detector modules increase the number
of gas species detected up to 24.
Fully automated software programs have been developed to
automatically operate the detector, control sampling, display
results, and record collected data. The LGA system is designed for
continuous operation with minimal maintenance, and all systems
include the ability to remotely monitor and assess system
performance.
Raman gas detection is significantly different from infrared-,
laser- or ultraviolet-based adsorption technology. Such systems
typically analyze no more than three gases per detector and can
measure only a limited range of gas concentration range. Unlike such
analyzers, the LGA system contains an integrated control computer,
gas sampling system and control system connectors. LGA installation
is much easier and installed system price is competitive with even
the lowest priced less capable technology.
