What do GC peaks signify?

GC = Gas Chromatography http://en.wikipedia.org/wiki/Gas_chromatography


Why volatile compounds are analysed in gc but not in hplc?

GC can give very resolved sharp peaks with short run time compared to hplc. additionally, there is less compatibility issue in setting an MS up to a GC than HPLC


Where do pristane and phytane appear in GC chromatogram?

Graham Howarth is correct. You can add carrier gas type, injection port temperature, gc column type (packed or capillary) and phase (too many to count),and a host of others. Without knowing the column phase I can't even suggest an elution order.


Why does hexane appear as more than one peak in gas chromatography?

Hexane is a mixture of 3 isomers out of a possible 5 isomers of 6 carbon alkanes. Normally there are 3 peaks for GC. Use a GC grade n-Hexane for one peak of the 'main' hexane.


What data does gas chromatography provide?

Gas chromatography (GC) provides data on the chemical composition of a sample. It separates and analyzes the individual components of a mixture based on their physical and chemical properties. The data provided by GC includes: Retention time: The time it takes for a compound to travel through the GC column and reach the detector. This can be used to identify the compound. Peak area: The area under the peak on the chromatogram represents the amount of the compound present in the sample. Peak height: The height of the peak on the chromatogram represents the concentration of the compound in the sample. Mass spectrum: GC can be coupled with mass spectrometry (GC-MS) to provide additional data on the molecular weight and structure of the compounds in the sample. Identification: GC can be used to identify individual compounds in a mixture based on their retention time and mass spectrum. This information can be compared to a database of known compounds to identify the unknown compounds in the sample.
