Yes this too belongs in the Forensic section, and again my reason is not many people go there! XP
How does gas and high performance liquid chromatography work? How much detail will we need to go into?
This is what I know of them...
Gas Chromatography:
Moving phase: carrier gas
Stationary phase: liquid on the sides of the tube
Advantage: fast
Disadvantage: need high temperatures to operate
HP liquid Chromatography:
Moving phase: liquid pumped into colum with solid particles
Stationary phase: surface of solid particles (chemically treated) in the column
Advantage: fast; can test substances that are heat sensitive unlike gas chromatography.
Disadvantage: cost of equipment
What else do we need to know?
