Method – Freezing Point Depression Osmometry
Osmometry measures the total molar concentration of dissolved solids in any solution. The freezing point of a solution is depressed in direct relation to the amount of solute in solution.
Uses and Applications – Emergency Medicine, Internal Medicine/Endocrinology, Urology/Renal Function, Surgery/Critical Care, Obstetrics/Gynecology, Pharmacy, General Quality Control.
