Question

List three general uses of gas chromatography in professional settings.

Answer 1

Determination of Pesticides, Residue in Aquaculture ProductsDetection and Quantitation by Gas ChromatographyAgricultural chemicals such as fertilizers and pesticides have made an importantcontribution to agriculture. Pesticides protect crops from pests and diseases.They have brought about large yield increases. since almost all chemicals that cankill pests are also potentially damaging to human health. Legislation requires thatpesticide use is appropriately controlled and maximum residue levels (MRLs) notbe exceeded.Detection method is the process of identifying the pesticides anddetermining their concentrations. With the aid of an analyticalinstrument, such as a gas chromatograph (GC), we can obtaininformation about the original sample by running a standardsolution containing the pesticide(s) at a known concentration andcomparing it with the sample.

2.For trace evidence, the ability to get the most information from the smallest sample provided, while preserving the maximumamount for other tests, is critical in delivering results to solve crimes.Gas chromatography mass spectrometry (GC/MS) is an important technique in thedetection and identification of both bulk drugs and trace level drugs in biologicalsamples.

3.analysis in a matter ofminutes and routine drugs analysis of fewdrugs In a matter of few seconds also possible.High sensitivity we see both rapid analysis aswell as high sensitivity.For ex is a 2 1/2 min of separation threecommon pesticides ,Methyl parathion,Malathion,Ethion at pg levels. Pg means 10-12 gramsthese areparts per billion. This is very goodexample of both the high speed as well as avery sensitive detection.Applications of gas chromatography:Gas chromatography (GC) is an instrumental technique used forensically in drug analysis,arson, toxicology, and the analyses of other organic compounds.The GC is one of popular instrument used in the world Several (applications)advantagesinclude.
