METHOD, COMPOSITION AND DEVICE FOR DETERMINING THESPECIFIC GRAVITY OR OSMOLALITY OF A LIQUIDABSTRACT OF THE DISCLOSUREA method and device for determining the specificgravity or osmolality of a liquid containing a nonionic,ionizable solute are disclosed. The method comprisescontacting the liquid with an ionizing agent, thus con-verting the solute to ionized species in the liquid, andcontacting the liquid with test means capable of producinga detectable response, such as a color response, dependentupon the specific gravity or osmolality of the ionizedliquid. The composition comprises an ionizing agent capable,upon contact with the liquid, of ionizing the solute therein,and a test means capable, upon contacting the liquid con-taining the solute in ionized form, of producing a detectableresponse which is a function of the specific gravity orosmolality of the liquid. The device comprises a carriermatrix incorporated with the test means and the ionizingagent.
