GC-MS是我們的一部分智能圖表系列。此外,它可以將化合物的複雜混合物分離出來以進行鑑定和定量。在氣相色譜法(GC)中,樣品被 ...
Gas Chromatography Mass Spectrometry analyses are performed on liquids, gases or solids. For liquids and gases, the sample is commonly directly injected into the GC. For solids, the analysis is carried out by solvent extraction, outgassing (desorption) or pyrolysis.
Desorption experiments are performed under helium flow at a controlled temperature between 40-300 ºC, with analytes being collected on a cryogenic trap during desorption. The sample chamber is a 1.25”x4” cylinder.
Pyrolysis is another sampling technique for the analysis of materials that cannot be directly injected into the GC-MS. By applying heat directly to the sample, the molecule can be broken down in a reproducible way. After that, GC-MS analyzes smaller molecules that reach the GC. By this method, probe temperatures of up to 1400ºC can be used.
In addition, many other sample preparation and sampling metho...
