NURSING ANM AND GNM

Detailed explanation-1: -Gas chromatography mass spectrometry (GC/MS) is an instrumental technique, comprising a gas chromatograph (GC) coupled to a mass spectrometer (MS), by which complex mixtures of chemicals may be separated, identfied and quantified.

Detailed explanation-2: -Helium gas is typically used as the carrier gas for GC/MS.

Detailed explanation-3: -GC-MS is an essential technology in modern analytical chemistry labs. Applications include development of new pharmaceuticals and analysis of their purity, detection of chemical warfare agents and explosives, screening of athletes’ urine for banned performance-enhancing substances, and analyzing soil samples on Mars.
