What is Gas Chromatography?

The gas chromatography technique is widely used in many industrial, research, environmental and forensic laboratories for the separation, identification, qualitative and quantitative analysis of analyte mixtures. Because its detection requires very small amounts of sample. GC requires compost to have thermal stability, sufficient volatility, or that certain analytes be in vapor form between 400 and 4500 C and not decompose at that temperature.

The analytes are injected into the injector by the hand syringe, as well as the autosampler, the samples enter as gas vapor, which is transported to a column, for the transport of the sample gas used as carrier gas. , the detector measures the response of each analyte.
