2019年10月13日 · Gas chromatography (GC) is an analytical technique used to separate and analyze samples that can be vaporized without thermal decomposition. Sometimes gas chromatography is known as gas-liquid partition chromatography (GLPC) or vapor-phase chromatography (VPC).
Gas Chromatography: Definition, Purpose, Detection, & Uses
Gas chromatography (GC) is a powerful analytical technique that separates and analyzes compounds in a gas phase. The instrument used for this process consists of a sample injector, a column where separation occurs, a detector to measure compound concentrations, and a data recording system.
