Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors. Find the best gas chromatographs in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Air SamplingAir sampling is described as the technique used to capture air for the subsequent purpose of analyzing, typically by thermal desorption, the presence of trace particulates, such as volatile organic compounds (VOCs).Airborne PollutantsAirborne pollutants are particulates, biological molecules or other harmful materials that exist in the atmosphere. These pollutants are known to cause harm to health and the environment. Examples include persistent organic pollutants (POPs), carbon monoxide, sulfur oxides, and nitrogen oxides.Volatile Organic Compounds (VOCs)Volatile organic compounds (VOCs) are chemicals that have a low boiling point. Some VOCs are harmful to human health, whereas others can be used to determine the shelf-life of foods samples. Semi Volatile Organic CompoundsSemi volatiles organic compounds (SVOCs) are a groups of compounds that have a low boiling point and evaporate above room temperature. SVOCs include phenols and polynuclear aromatic hydrocarbons (PAH).
