Gas Chromatography - Mass Spectrometry (GC-MS)
Gas Chromatography-Mass Spectrometry (GC-MS) is a method that combines the characteristics of gas chromatography and mass spectrometry to identify different substances in samples, which can be used for qualitative analysis of multi-component mixtures in a short time. GC-MS is mainly used in industrial testing, food safety, environmental protection and many other fields, such as pesticide residues, food additives, textile testing, electronic and electrical products testing, physical evidence testing may involve a variety of complex compounds, GC-MS instruments provide strong support for the qualitative and quantitative analysis of these complex compounds in the process of judicial identification.
Composition of GC-MS
- Gas Chromatography (GC) has strong separation ability.
- Mass Spectrometry (MS) has a unique ability to identify unknown compounds with high sensitivity, so GC-MS is one of the most powerful tools for the separation and detection of complex compounds.
- When the GC-MS is used, the GC is the ideal separator for the MS, and the MS is the ideal detector for the GC.
- The volatile substances are separated and quantified by GC, and the composition and structure are analyzed by MS by measuring the mass and strength of ions.
- GC has high separation efficiency and accurate quantification, while MS has high sensitivity and strong qualitative ability, and almost all organic compounds can be detected.
Applications & industries
- Doping testing
- GC-MS is used to study the process of drug synthesis and the mechanism of drug action, so as to prepare for the study of drug pharmacology and toxicology, and provide a basis for drug quality control and the formulation of drug quality standards.
- Application in volatile ingredients and active ingredients of traditional Chinese medicine
- Pesticide residue testing
According to the requirements of the International Olympic Committee Medical Committee, the only instrument that can be used to confirm doping in sports is GC-MS. General doping testing laboratories use GC-MS for preliminary screening.
Applying GC-MS technology to volatile components and effective components of traditional Chinese medicine, combining the high-efficiency online separation capabilities of gas chromatography with the high-selectivity and high-sensitivity detection capabilities of mass spectrometry, can be used as a pharmacodynamic research method for the separation and analysis of complex systems.
GC-MS technology can confirm and identify the structure of many kinds of pesticides, and mass spectrometry detector can carry out qualitative and quantitative analysis and positive confirmation of various types of residues at the same time. Combined with the application of ion monitoring technology and the development of efficient and rapid methods, the interference of impurities can be eliminated and the analysis sensitivity can be greatly improved.
