What does GC stand for forensics?

What does GC test stand for?

Gas chromatography can also be conducted as a stand-alone test in order to determine the purity of a substance, or to separate different components of a mixture. In order to conduct gas chromatography, scientists first inject the analyte, a liquid or gaseous sample, into a gas chromatograph (pictured).

What does GC mean in lab?

Gas chromatography (GC) is an analytical technique used to separate the chemical components of a sample mixture and then detect them to determine their presence or absence and/or how much is present.

What is GC in pregnancy?

What is a gonorrhea test? Gonorrhea is one of the most common sexually transmitted diseases (STDs). It is a bacterial infection spread through vaginal, oral, or anal sex with an infected person. It can also be spread from a pregnant woman to her baby during childbirth. Gonorrhea can infect both men and women.

What does GC MS stand for in drug testing?

The most sophisticated drug-testing approach is gas chromatography coupled with mass spectrometry (GC/MS), which is regarded as a “gold standard”; it is used in confirmatory testing.

What is mass spectrometry in drug testing?

Mass spectrometry (MS) is the most discriminatory of the drug testing techniques. Mass spectrometry measures the precise molecular mass of ions as determined by their mass to charge ratio (m/z) and is the current gold standard in forensic drug analysis [17].

What is GC in medical terms?

Gas chromatography (GC): A type of automated chromatography (a technique used to separate mixtures of substances) in which the mixture to be analyzed is vaporized and carried by an inert gas through a special column and thence to a detection device.

What is the principle of GC?

Principle of gas chromatography: The sample solution injected into the instrument enters a gas stream which transports the sample into a separation tube known as the “column.” (Helium or nitrogen is used as the so-called carrier gas.) The various components are separated inside the column.
