A Review on GC-MS Hyphenated Technique

The hyphenated technique is developed from the coupling of a separation technique and an on-line spectroscopic detection technology, GCMS, LC-MS, LC-FTIR, LC-NMR, and CE-MS. Gas chromatography combined with mass spectrometry is an important technique for identification and quantification of analytes in multifactor systems. GC-MS is highly effective and versatile analytical techniques with numerous scientific applications to cater the field of applied Sciences and Technology. This review elaborates the significant uses of this technique. It includes a brief discussion of the instrumental set-up and theory for the comprehensive GC × GC hyphenated with different detection techniques. It is fast and sensitive, provides a high peak capacity, and allows determination of thermally stable and volatile compounds.
