WQA-3600 Automatic Water Quality (Volatile Organic Compounds) Analyzer

Product Overview

The WQA-3600 water quality (volatile organic compounds) automatic analyzer consists of a headspace sampling module and a high-temperature chromatographic analysis module (GC-FID). Can monitor volatile organic pollutants such as benzene, toluene, xylene, ethylbenzene, styrene, etc. in industrial wastewater and surface water cross-sections. The water sample is drawn into the headspace pool of the analyzer through a pre-treatment pipeline. Under constant temperature heating, the volatile organic compounds in the water sample are transferred to the gas phase space above the liquid surface, and then pressurized and depressurized by a carrier gas. The volatile sample gas is transferred to the high-temperature chromatographic analysis module for detection. By using the headspace sampling device to convert liquid phase to gas phase, the emitted clean gas can be directly measured, overcoming the influence of impurities such as suspended solids in water on the analysis flow path.

Product Features

By using the headspace sampling device to directly measure the clean gas emitted during the liquid to gas phase transition process,Overcoming the influence of impurities such as suspended solids in water on the analysis airflow path
Each time the injection is completed, the analyzer automatically backblows the chromatographic column, accelerating the screening of component analysisThe speed
The intelligent FID detector automatically ignites when the flame is turned off, effectively controlling the safety of the hydrogen flame gas path
The chromatograph supports multi-point sampling, with low investment, low operating costs, and simple maintenance
The internal pipeline of the chromatograph has undergone silane treatment, greatly reducing the absorption of gas samples in the tube wallResidual attachment

Application field

Suitable for monitoring volatile organic compounds in wastewater discharge from industries such as coatings, resins, and pharmaceuticals, as well as in centralized drinking water and surface water sources.
