Principle

Gas Chromatography – Mass Spectrometry (GC-MS) is a powerful analytical technique that combines the ability of Gas Chromatography in separate complex mixtures with the detection capability of Mass Spectrometry.

The compounds coming from the chromatographic column reach the Mass Spectrometer and are ionized and analyzed by mass to charge ratio. Structural information are obtained by fragmentation of the molecular ion to generate fragments of lower molecular weight.

Each component is detected as a chromatographic peak (ideally with Gaussian shape) and the area of the peak is used for quantification, generally with a calibration line (using response factors). GC-MS allow quantification with low sensibility (ppb-ppm range) and high selectivity and specificity.
