Agilent 490 Micro-GC Biogas Analyzer User Manual
The Agilent 490 Micro-GC Biogas Analyzer is a factory-configured instrument designed for the analysis of pure biogas, permanent gases, hydrogen sulfide, and hydrocarbons up to n-propane. The system consists of a dual housing equipped with a CP-Molsieve 5A and a CP-PoraPLOT U column for two carrier gases. An extended version is also available for analyzing mixtures of biogas and other hydrocarbon streams up to n-heptane. This manual is written in German.
