What is gas chromatograph?

Gas chromatography (GC) is an analytical technique used to separate and analyze volatile substances in a sample. The sample is vaporized and injected onto a chromatographic column. The components are separated based on their boiling points and interactions with the column's stationary phase. As each component exits the column, it is detected, and a chromatogram is generated, showing the presence and quantity of each component. GC is commonly used in environmental monitoring, food safety, pharmaceuticals, and forensic science.

What other technologies are related to gas chromatograph?

gas chromatograph Competitor Technologies

TLC plate scanner

TLC plate scanners are used for quantitative analysis of compounds separated by thin-layer chromatography, offering an alternative separation and analysis technique to gas chromatography.

High Pressure Liquid Chromatograph

HPLC is a separation technique that, like GC, is used to separate and quantify components of a mixture. They are competitors because they are used for similar purposes but are better suited for different types of compounds (HPLC for non-volatile, thermally labile compounds).

spectrophotometer

Spectrophotometers measure the absorbance or transmission of light through a sample. They are an alternative analytical technique to GC, though GC is more powerful for separating and quantifying components of a mixture.

ICP

ICP (Inductively Coupled Plasma) is an elemental analysis technique. It serves as a competitor, as it provides information on elemental composition, albeit through a different method than GC, which analyzes volatile organic compounds.
