Inverse gas chromatography experiments, where the mobile and stationary phases are reversed, are often performed at the “infinite” limit of this process. For 10 points each:
[10e] Name this process of adding more solvent to a solution to lower its solute concentration.
ANSWER: dilution [accept word forms like diluting; accept infinite dilution]
[10h] Inverse GC is mainly used to compute this quantity for solid analytes. Ostwald ripening is driven by large values of this quantity that scale linearly with the critical radius of nucleation.
ANSWER: surface energy [or surface free energy; or interfacial energy; accept surface tension; prompt on partial answers]
[10m] Inverse GC may require using a James-Martin correction to calculate the “[this word] volume.” The square of the “[this word]” time divided by peak width equals theoretical plate number in the Van Deemter equation.
ANSWER: retention [accept retention volume or retention time or retention factor]
