The Model 4020 uses a field-proven FID detector to measure THC in various streams. This instrument is ideal for monitoring hydrocarbon contamination in high purity bulk gases. When coupled with Teledyne’s unique separation column, the 4020 is also diverse enough to be applied in hazardous locations for detection of volatile hydrocarbons in cooling water for process leak detection and environmental compliance.
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
