a) Compounds with low boiling points tend to spend less time in the gaseous state than compounds with high boiling points. b) Components that preferentially reside in the gas phase will exit the GC column later than those that interact more strongly with the stationary phase. c) To separáte a mixture by GLC, the first step is to inject the mixture into a heated port on the instrument, to vaporize the mixture. Od) Similar to thin-layer chromatography, in gas chromatography, certain compounds will interact more with the stationary phase than others will. Oe) In gas chromatography, the mobile phase is a gas, and the stationary phase is a very high boiling-point liquid absorbed onto a solid support.
