COMPOSITION FOR MEASURING IONIC STRENGTH OR SPECIFIC GRAVITY OF LIQUID SPECIMEN AND TEST PIECE PREPARED FROM SAID COMPOSITION

摘要

A composition for measuring the ionic strength or specific gravity of a liquid specimen and to a test piece prepared from said composition. Specifically, the invention concerns a composition constituted of, for example, one weight percent of heparin sodium in refined water and 1 mM of Methylene Blue, and a test piece in which test paper consisting of filter paper which is impregnated with a solution of said composition, dried, and cut to size is stuck to a plastic piece. The use of said composition and test piece enables easy, simple, quick but exact measurement of the ionic strength or specific gravity of a liquid specimen without influenced by the characteristics of said specimen, such as pH and temperature.
