Freezing-point depression
This kind of measurement is called cryoscopy (Greek cryo = cold, scopos = observe; "observe the cold") and relies on exact measurement of the freezing Cryoscopy is no longer as common a measurement method as it once was, but it was included in textbooks at the turn of the 20th century. wikipedia.org

Colligative properties
Freezing point depression (cryoscopy) The freezing point () of a pure solvent is lowered by the addition of a solute which is insoluble in the solid solvent , and the measurement of this difference is called cryoscopy. wikipedia.org

Boiling-point elevation
depression is larger than the ebullioscopic constant, and since the freezing point is often easier to measure with precision, it is more common to use cryoscopy wikipedia.org

Molality
frequently used in medical laboratory results in place of osmolarity, because it can be measured simply by depression of the freezing point of a solution, or cryoscopy wikipedia.org
