4040 Methane/Non-Methane Analyzer

Gas Analyzers

Model 4040
Methane/Non-Methane Analyzer

Description

The Model 4040 is a microprocessor-based, oven heated methane/non-methane gas analyzer designed to measure varieties of hydrocarbon concentrations from a sampling point.

4000 Series Overview:

All 4000 series units employ the same basic architecture and electronics; however, each analyzer has additional features:

4020 Total Hydrocarbon Analyzer	Uses FID to measure total hydrocarbons in ppm in a sample gas stream
4030 Total Hydrocarbon Analyzer	Basic 4020 with sample system at a higher temperature for heated applications Avoids condensation of the sample
4040 Methane / Non-Methane	Basic 4020, plus temperature-controlled sampling system with GC column to give accurate readings of both methane and non-methane hydrocarbons in a gas stream
4060 Benzene Analyzer	Same as 4040, but used to measure ppb levels of benzene instead of methane/non-methane
4080 Total Hydrocarbon Analyzer	Basic 4020 with sample system including stripper to measure total hydrocarbons in an aqueous sample

Features

Easy to use software, user programmable ranges
GC technology used for complete separation of Methane, Ethylene Oxide, Benzene, Styrene, BTX and many other compounds (application dependent)
