Chromatography
Gas Chromatography Mass Spectrometry (GC/MS) links the analytical capabilities of Gas Chromatography and Mass Spectrometry to separate and then identify different substances within a sample.
Gas Chromatography Mass Spectrometry can be used to analyze and identify unknown samples, identify trace components in complex mixtures, and to analyze volatile or semi-volatile compounds.
Approaches
GC/MS can be used to identify unknown samples. Quantitative analysis to part-per-billion (ppb) levels can be accomplished.
GC/MS can identify trace components in complex mixtures. The analytical techniques, used together, can provide a more definitive substance identification and quantification than either the Gas Chromatography or Mass Spectrometry method used separately.
Gas Chromatography/Mass Spectrometry analysis of volatile or semi-volatile compounds can be achieved using headspace techniques or extraction and liquid injection techniques.
Sample Considerations
Volatile and semi-volatile compounds can be analyzed using this method.
The sample size can vary but 2 grams is generally sufficient.
