GC / MS Analysis (gas chromatography / mass spectrometry)

[Gas chromatography is one of the most important methods in instrumental analysis of organic compounds and is used in areas such as medicine, biology, food chemistry, environmental analysis and forensics. GC / MS is the coupling of a gas chromatography device (GC) with a mass spectrometer (MS The gas chromatograph is used to separate the substance mixture to be examined and the mass spectrometer to identify and, if necessary, quantify the individual components. The column of a gas chromatography device consists of a thin tube or capillary as the stationary phase and an inert gas flows through it as the mobile phase. The substance mixture, which is also gaseous and consists of neutral molecules, is injected into this gas flow.

Each component of the substance mixture has a characteristic running speed, so that the mixture is separated into individual substances based on their retention time.]

Application of Gas Chromatography - GC / MS Analysis

Do you want to have ingredients analyzed? Gas chromatography is a very sensitive method for analyzing mixtures of substances. It can be used to separate complex mixtures of substances into individual components. In many cases, the retention time alone is sufficient for a substance to be identified from the time it is injected to the point of passage through the detector. By combining it with a mass spectrometer, the so-called GC / MS coupling, very small amounts of substance can be detected and at the same time structure elucidation is carried out After calibration, the integrated peak area of the substance allows a conclusion to be drawn about its mass fractions in the sample.

Gas chromatographic methods are suitable for determining all volatile or vaporizable organic substances.
