Trihalomethanes (THMs) are critical contaminants in drinking water and ultrapure water (UPW) and require monitoring as well as efficient removal.
Ecolab® Ultra-Pure Water+ 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.
Ecolab Ultra-Pure Water+ THM Analyzer 1501 is a unique analyzer which is able to give measurements at real time in potable water, process and UPW with the aim to control THM removal processes or water disinfection processes.
The THM Analyzer 1501 is able to measure several common THMs such as: Trichloromethane (Chloroform) CHCl3, Bromodichloromethane CHCl2Br, Dibromochloromethane CHClBr2, Tribromomethane (Bromoform) CHBr3.

Headspace gas chromatography with highly reliable and sensitive PID/TID detectors.
Ecolab Ultra-Pure Water+ 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.
Urea Analyzer
Urea is a critical contaminant in ultrapure water (UPW) for semiconductor manufacturing because it contributes to total organic carbon (TOC) concentration and can adversely affect photolithography processes.
