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 40​​20 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​
