Toxic gas analyzer
GOW-MAC Instrument Co.
The principle of this automated, fully digital instrument is based on aqueous scrubbing of the target gas by a coil sampler coupled with a gas-liquid separator, followed by derivatization of the analyte to form a highly light-absorbing chromophore in an on-line reactor. The derivative then is quantified by a colorimetric detector.
Any gas species with potential to be derivatized can be determined by the Series 900 Toxic Gas Analyzer; e.g.: HF, NH3, H2CO, HONO, HCl, SO2, H2S, HCHO and aldehydes, etc. The analyzer is not only able to determine trace level toxic gases in air, but also to quantify the ppb/ppm level impurities in industrial processing and electronic gases, such as N2, N2O, NF3, CxHy, etc. Custom applications based on your specific needs are available for evaluation by request.
