zNose® based upon ultra-fast gas chromatography, simulates an almost unlimited number of specific virtual chemical sensors, and produces olfactory images based upon aroma chemistry. The zNose® is able to perform analytical measurements of volatile organic vapors and odors in near real time with part-per-trillion sensitivity. It is can be used as a useful environmental tool for quantifying the concentration of 2-Methylisoborneol and Geosmin in pond water samples to facilitate Aquaculture.
