Micro GC Biogas Analyzers

Biogas is produced by the anaerobic bacterial breakdown of organic matter. The feedstocks of biogas include different types of organic material. Wastewater, manure, organic industrial waste, and energy crops are the most common feedstocks.

There are two types of analyzers based on the 990 Micro GC platform for biogas analysis. The 990 Micro GC biogas analyzer is recommended for pure biogas analysis. It consists of two analytical channels. One is a 10 m Agilent J&W CP-Molesieve 5Å channel for permanent gas, carbon monoxide, and methane analysis, the other is a 10 m Agilent J&W CP-PoraPLOT U channel for carbon dioxide and hydrogen sulfide analysis.
