Gas-solid chromatography is based on which of the following processes?

1.	Gas-solid chromatography is based on which of the following processes?(a) Partition of the analyte between a gaseous mobile phase and a stationary liquid phase(b) Adsorption of gaseous substances on solid surface(c) Ion exchange(d) Large molecules cannot penetrate through the gelThe question was posed to me during an interview.I'm obligated to ask this question of Gas Solid Chromatography in division Chromatography of Analytical Instrumentation
Answer» The correct CHOICE is (b) Adsorption of GASEOUS SUBSTANCES on solid SURFACE The BEST explanation: Gas-solid chromatography is based on the adsorption of gaseous substances on a solid surface. It is useful for the separation of rare gases.
