THM Analyzer 1501

Designed to Control THM Removal and Water Disinfection Processes

Trihalomethanes (THMs) are critical contaminants in drinking water and ultrapure water (UPW) and require monitoring as well as efficient removal.

Ovivo Ultra-Pure Water+ by Ecolab THM Analyzer 1501 provides real-time measurements in potable water, process water and UPW with the aim of controlling THM removal processes or water disinfection processes.

How It Works

Headspace gas chromatography with highly reliable and sensitive PID/TID detectors.

Ovivo by Ecolab THM Analyzer 1501 consists of a gas chromatograph (GC) with thermal ionisation detector (TID) and photo ionisation detector (PID) connected to an industrial computer equipped with analytical software for the evaluation and documentation of the measurements.

The water sample passes through a multiplexer to a sample preparation unit, the operation of which is based on a headspace method. The sample is heated for a defined period of time at a set temperature and the volatile substances from the sample enter the gas phase. When a balance between the liquid and the gas phase is reached, the resulting overpressure forces the gas towards the sample loop of the gas chromatograph.

The individual compounds are analyzed using separation columns and detectors (PID and TID) which generate signals displayed on chromatograms. The concentration of the compounds are then calculated by evaluation software through determination of respective peak height and integration of peak surface.
