Thermo - I Series 55i NMHC

Thermo - I Series 55i NMHC - Non Methane Hydrocarbon Monitor

Make automated measurements of methane and non-methane hydrocarbons with the Thermo Scientific™ Direct Methane & Non-Methane Hydrocarbon Analyzer, Model 55i. Unlike instruments that measure only methane and total hydrocarbons, this back-flush gas chromatography (GC) system provides a direct measurement of non-methane concentrations.
