Thermo 55C
The Thermo 55i & 55c hydrocarbon analyzer is a back-flush gas chromatography (GC) system designed for automated measurement of methane and nonmethane hydrocarbons. The back-flush GC method used by the Model 55i provides a direct measurement of non-methane concentrations.
This allows accurate and precise measurement of low levels of non-methane hydrocarbons (NMHC), even in the presence of methane at much higher concentrations. The proprietary column design is unaffected by the oxygen content of the sample, provides complete recovery of low volatility compounds and achieves absolute separation of methane from all C2 compounds.
