Hint:
Gas chromatography 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. In gas chromatography, the mobile phase (or moving phase) is a carrier gas , usually an inert as such as helium or an unreactive gas such as nitrogen
Complete step by step answer:
- Gas chromatography is most commonly used for the separation and analysis of compounds that can be vaporized without decomposition.
- Whereas, Gas liquid chromatography runs on the principle of partition. In GLC the components of vaporize samples are fractionated due to partition between a gaseous mobile phase and a liquid stationary phase held in the column.
- So, this is a fast separation of complex mixtures and allows for quantitative determination of each compound.
Hence, option C is correct.
Additional information
In gas liquid chromatography,
1.Analyte (sample) is brought in by the syringe into a heated injection chamber.
2.Nitrogen gas ( inert ) flows through carrying sample into the column
3.Column has thin film or liquid
4.After separation the carried gas and separate mixture flows in detector which activates a recorder
5.Traces a series of peaks on chromatogram
Note:
Carrier gas is an inert gas used to carry samples. Helium and nitrogen are most commonly used and the use of helium is desirable when using a capillary column.
