2021/03/21 · In gas-liquid chromatography, a stationary phase is liquid that is immobilized on the surface of a solid support by adsorption or by chemical bonding. Gas chromatographic separation occurs because of differences in the positions of adsorption equilibrium between the gaseous components of the sample and the stationary phases (Figure \(\PageIndex{9}\)).

2019/08/13 · Headspace gas chromatography is also known as liquid-gas chromatography. It has the characteristics of faster analysis speed, no need to extract with an organic solvent, easy operation, and little harm to analysts and Fig. 1. 1.

2013/04/08 · A new detection method using headspace single-drop microextraction (HS-SDME) coupled to gas chromatography (GC) was established to determine the iodine in milk powder and urine. The derivative from the reaction between iodine and butanone in the acidic media was extracted into a micro-drop then determined by GC-ECD. With the optimisation of HS-SDME and derivatisation, the calibration
