click to zoom

Precisive® 5 Trace VOC/Hydrocarbon Analyzer is an infrared absorption based on-line monitoring system configured for measurement of hydrocarbon and VOC gases; including alkanes, alkenes, alkynes, alcohols, aldehydes and aromatics at ppm to percent levels.

This is a real-time optical analyzer capable of performing compound speciation or separation which previously could only be performed by Gas Chromatograph (GC) analyzers. Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to 1 second intervals are executed for full compound speciation and detection of the customer specific compound set.

Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. The Precisive Trace Hydrocarbon/VOC Analyzer does not require carrier gas, fuel gases or on-site calibration gases.
