Agilent 450-GC CO/CO2 Analyzer Manual
The Varian 450-GC CO/CO Analyzer is designed for the accurate and reliable trace analysis of carbon monoxide, methane, and carbon dioxide in gas mixtures. It features detection limits down to low ppb levels and is available in two configurations: one optimized for hydrocarbon matrices like ethylene or propylene, and another with an enlarged sample loop for pure gases such as hydrogen, helium, and nitrogen.
The system incorporates proven hardware and column technology based on the Varian 450-GC platform. It utilizes a single channel, multi-dimensional packed column configuration with injection via gas sampling valve and detection using a methanizer and FID in series. The analyzer is fully automated for walk-away operation and includes operational procedures documented for regulatory compliance.
