Chemistry - Gas chromatography (GC)
Gas chromatography (GC)
GC operates at much higher temperatures than HPLC. The sample is injected
into the instrument either as a gas or a liquid (which is immediately
vaporised). The significant difference from HPLC is that the mobile phase
is a gas, often called the carrier gas, and the column is much longer.
