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.
