Description

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
