Online automatic measurement of volatile organic compounds (VOCs) in river water, factory wastewater, etc.
Headspace - This method automatically measures volatile organic compounds (VOCs) in river water, industrial wastewater, and other water sources online using gas chromatography. Hydrocarbons such as benzene and toluene are measured with a hydrogen flame ionization detector (FID), while halogenated compounds like trichloroethylene and tetrachloroethylene are simultaneously measured with a non-radioactive electron capture detector (EN: optional). The entire series of operations from "sampling water → gas-liquid equilibrium → headspace sampling → GC measurement → discharge" is fully automated.

basic information
- Simultaneous measurement of multiple components is possible using gas chromatography. - Measurements can be taken down to concentrations below ppb with two detectors: FID and EN. (Note: EN is optional) - The operation is fully automated, controlling all processes from sampling to GC measurement and wastewater disposal. - The headspace section is in a transparent container, allowing visual confirmation of the operation process. - Water leak prevention measures are thorough with a leak alarm system. - Measurement results are transmitted to higher-level DCS, etc., via 4-20mA.
