How Does Gas Chromatography Work?

Why use an EST gas chromatographer? EST's high speed gas chromatography employs patented techniques to separate chemicals in near real time so that pattern recognition and trace detection can be performed in seconds. Unlike trace detectors which only detect a few select compounds, electronic noses recognize odors and fragrances based upon their full chemical signature.
