Definition
Meaning and Definition
A laboratory technique for separating and analyzing volatile compounds by partitioning them between a mobile gas phase and a stationary liquid phase.
A specific form of partition chromatography, essential in analytical chemistry, biochemistry, and forensic science, used to identify and quantify the components of a mixture based on their differential interaction with the liquid stationary phase.

Common Mistakes When Using “gas-liquid chromatography”
- Confusing it with 'gas chromatography' (the wider category).
- Writing 'gas liquid chromatography' without the hyphen, which can slightly obscure the compound noun structure.
- Using it as a verb (e.g., 'We gas-liquid chromatographed the sample' is highly non-standard; prefer 'We analysed the sample by gas-liquid chromatography').
FAQ
Frequently Asked Questions
No, gas-liquid chromatography (GLC) is a subset of gas chromatography (GC). GC includes both GLC (liquid stationary phase) and gas-solid chromatography (GSC, solid stationary phase).
GLC is ideal for volatile and thermally stable compounds, such as hydrocarbons, fragrances, solvents, and many organic molecules that can be vaporised without decomposition.
The hyphen links 'gas' and 'liquid' to form a single conceptual unit modifying 'chromatography'. It clarifies that the technique involves a gas mobile phase and a liquid stationary phase, not chromatography of a gas-liquid mixture.
Because separation is based on the partition (distribution) of analyte molecules between two immiscible phases: the moving gas phase and the stationary liquid phase, analogous to a liquid-liquid extraction.
A laboratory technique for separating and analyzing volatile compounds by partitioning them between a mobile gas phase and a stationary liquid phase.
Gas-liquid chromatography is usually technical/scientific in register.
Gas-liquid chromatography: in British English it is pronounced /ɡæs ˈlɪkwɪd ˌkrəʊməˈtɒɡrəfi/, and in American English it is pronounced /ɡæs ˈlɪkwɪd ˌkroʊməˈtɑːɡrəfi/. Tap the audio buttons above to hear it.

Mnemonic
Think: Gas (carrier) Liquid (sticky film) CHROMATOGRAPHY (colour writing - original method). It separates a mixture like runners (compounds) on a track with a sticky lane (liquid phase), each getting slowed down differently.
Conceptual Metaphor
A high-precision race where different compounds are runners (solutes), the track is a long column (system), the wind is the carrier gas (mobile phase), and the sticky surface of the track is the liquid coating (stationary phase) that slows each runner uniquely.
