Analytical Chemistry – GC Mass Spectrometry
Posted on April 12, 2022 Analytical Chemistry
Gas Chromatography – Mass Spectrometry (GC-MS) is an analytical technique that combines the power of GC separation with MS detection for the identification of compounds within a sample. A mixture of compounds is separated using gas chromatography, and each of the separated compounds is then ionized. The resulting fragmentation pattern can then be used to deduce the chemical structure of the separated compound. Nominally used in liquid or liquid-extraction samples, GC-MS can also be used for gaseous or solid-fraction analysis by mobilizing via solvents or direct injection into the GC. These approaches increase the ability to identify trace compounds and ions in a sample.
Coanda’s analytical lab employs GC-MS in its broad suite of analytical techniques and instrumentation supporting #cleantech development. The instrument is useful in understanding chemical interactions and the resulting process compositions, enabling the identification of problematic compounds in cleantech applications. Compound identification is the first step to finding solutions to these challenging problems.
