Product Description

Printer Version

The Transportable Analyzer System is designed to monitor a gas process for gas composition, temperature and pressure. The system includes electrically powered equipment to sample toxic, flammable, possibly explosive gases and uses high-pressure gas cylinders for calibration.

The system is housed within two NEMA 4 electrical enclosures that are permanently mounted on a four-wheel cart.

The heart of the system is ARI’s Laser Gas Analyzer (LGA), which is a self-contained gas sampler/analyzer that uses the principles of Raman spectroscopy to simultaneously identify and quantify eight (8) gaseous compounds. The system connects the analyzer to eight (8) gas-sampling ports via a unique valve manifold. Sample scheduling, which is user configurable, generally cycles continuously through the eight ports, one after another. Sample time at each port is typically 10 to 15 seconds.

The system includes ARI’s multi-port-purge system that uses an auxiliary pump to simultaneously pre-purge one or more sample lines while concurrently analyzing gas in a specified line. This shortens the time between port-gas measurements by keeping the sample lines filled with fresh sample gas. The system also includes ARI’s nitrogen back flush system. Should any of the eight sampling lines become restricted or plugged, pressurized nitrogen can be forced backwards down the line to clean it.

The transportable unit includes on-board calibration gases for daily calibration. The system also optionally includes temperature and pressure monitoring. The sample site may be at the same location as the gas measurement or at a different location.
