Total Hydrocarbon Analyzer
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
