GC-FID International analysis method
Conformance to industrial standard
The Online Monitoring System for Volatile Organic Compounds in Water, based on the GC-FID analysis method, integrates fully automatic functions such as water collection, purging and capturing, sample analysis, data collection and transmission, quality control, etc. It is widely used in the fields of drinking water sources, surface water, groundwater, municipal sewage, and industrial wastewater, achieving real-time and online monitoring of volatile organic compounds in various water bodies from ppm to ppb level, and achieves timely warning.
☆ GC-FID: Water Quality - Determination of Volatile Organic Compounds - Purge and Trap/Gas Chromatography (HJ 686)
☆ Constant-temperature purging: high purging efficiency, small purging gas consumption, long maintenance cycle and low maintenance cost
☆ Efficient physical water removal: effectively prevent water vapor from entering the chromatographic separation system, ensuring qualitative stability
☆ Automatic cleaning function: Water sample collection pipe, purging chamber, and organic matter collection tube have automatic cleaning function, and the system memory effect is small
☆ Combination filling trap: high capture efficiency, multiple types of capture, high sensitivity, and multiple components detected in a single test
☆ DC heating desorption technology: fast heating to avoid peak broadening introduced by thermal desorption, and good chromatographic separation effect
