Analytical detection of hazardous chemicals in enviromental water samples is challenging due to complex mixtures and trace concentrations of contaminants. This application shows an accurate GC-MS method for indentification and control of volatile and semi-volatile organic pollutants in drinking water, surface water and wastewater.
Total petroleum hydrocarbons index (TPH) is a typical environmental analysis. It has replaced the infrared spectroscopy method using problematic solvents, i.e. Freons. This gas chromatography analysis (GC) monitors hydrocarbons between n-decane and n-tetracontane. These two hydrocarbons are used as the range marker and injection efficiency control. Aditionally, the GC method has an important advantage – this can show a type of hadrocarbon contamination (e.g. gasoline, naphtha, motor oil) and weathering status (some n-alkanes disappear during their stay in the enviroment).
