An eluotropic series (a) ranks solvents by their relative abilities to displace

Question

An eluotropic series (a) ranks solvents by their relative abilities to displace solutes from a given absorbent. (b) ranks column packing material by their relative abilities to retain solutes on the column. (c) is a measure of the solvent adsorption energy. A new chromatographic method should have the following attributes (a) adequate resolution of the desired analytes, a short run time, and not drastically affected by variations in conditions. (b) adequate resolution of the desired analytes, a short-run time, not drastically be effected by variations in conditions, and use a reversed-phase column for versatility. (c) determine a goal, select a method of sample preparation, and choose a detector. Dwell (Dead) volume is defined as (a) the volume of solvent contained in a liquid chromatographic column. (b) the time required for the gradient to reach the column. (c) the volume of the column between the point at which solvents are mixed and the beginning of the column.
