Using Ultra-Fast Electronic Nose for Testing Pollutants in Air, Water and SoilBy Electronic Sensor Technology
The whitepaper describes how a new type of electronic nose, the zNose, is used for measurement of volatile organic compounds in water.
Based upon ultra-fast gas chromatography, the zNose is able to perform analytical measurements of volatile organic vapours in near real-time with part-per-billion sensitivity.
Separation and quantification of the individual chemicals within water samples is performed in seconds. Using a patented solid-state mass-sensitive detector, picogram sensitivity, universal non-polar selectivity, and electronically variable sensitivity is achieved.
An integrated vapour pre-concentrator coupled with the electronically variable detector, allows the instrument to measure VOC concentrations spanning 6 plus orders of magnitude.
