Solvent for preparation of analytical sample

Abstract

A solvent for use in the preparation of an analytical sample includes at least one component selected from the group consisting of polyvalent alcohols, sugars, and hydrophilic polymers, and has a boiling point at one atmosphere of from 101° C. to 300° C. The solvent facilitates the preparation of samples for use in analyzing extremely small quantities in analytical devices having capillary channels. By virtue of its boiling point, the solvent can prevent the concentration of analytical samples without requiring special devices or tools, even when a minute quantity of sample solution is left for a long period of time or is placed in a high-temperature environment.
