How does gas chromatography work?
How Gas Chromatography Works First, a liquid sample is prepared. The sample is mixed with a solvent and is injected into the gas chromatograph. Typically the sample size is small — in the microliters range.
How do you prepare a gas chromatograph sample?
First, a liquid sample is prepared. The sample is mixed with a solvent and is injected into the gas chromatograph. Typically the sample size is small — in the microliters range. Although the sample starts out as a liquid, it is vaporized into the gas phase.
How does gas chromatography determine purity?
How does gas chromatography determine purity? GC is used as one test to help identify components of a liquid mixture and determine their relative concentration. It may also be used to separate and purify components of a mixture. Chromatography can test blood alcohol, drug purity, food purity, and essential oil quality.
What is the other name of gas chromatography?
Sometimes gas chromatography is known as gas-liquid partition chromatography (GLPC) or vapor-phase chromatography (VPC). Technically, GPLC is the most correct term, since the separation of components in this type of chromatography relies on differences in behavior between a flowing mobile gas phaseand a stationary liquid phase.
