About the GC-MS Facility
The Gas-Chromatography-Mass Spectrometry (GC-MS) facility has been funded by MKU-RUSA 2.0 under a research project entitled "Molecular Design and Development of Imaging Agents and Inhibitors: A Chemical Biology Approach" (007-R2/RUSA/MKU2020-2021). This facility was established in 2022. This GC-MS facility is available at Dept. of Natural Products Chemistry, School of Chemistry, Madurai Kamaraj University, Madurai.
Gas-Chromatography-Mass Spectrometry
GC-MS is a highly-sensitive detection technique that forms, separates and detects ions in the gaseous phase. It can perform both quantitative and qualitative analyses. GC-MS separates and quantifies multi-component samples and complex matrices and can identify unknown compounds. Both FID and MS detectors can quantitate using the peak intensity or peak area and identify compounds using the retention time from the chromatograms. This is extremely valuable for the unique identification of molecules, also known as qualitative analysis.
