WebSep 26, 2024 · Understanding how osmometers work first requires a basic understanding of the differences between osmolality (mOsm/kg) and osmolarity (mOsm/L). As mentioned, osmolality is a measure of a solution’s particle concentration by weight. Osmolarity is different in that it determines the total number of particles in a solution per unit of volume. WebJun 28, 2015 · Osmolality = ΔT / -1.86 where ΔT is the measured depression of the freezing point, and -1.86 is the cryoscopic constant for water, which is just another way of saying that one mole of solute added to 1kg of water will depress its freezing point by 1.86º K.

WebPlasma osmolality less than 285 mmol/L confirms the presence of true (hypotonic) hyponatremia (Hoorn et al., 2005).Besides plasma osmolality, ascertaining volume status helps to narrow the differential diagnosis.
