An osmometer measures osmolality from the concentration of a substance in a solution. A freezing point osmometer, as designed and manufactured by Precision Systems, determines concentration of a solution by measuring the freezing point of the solution, as freezing point is directly correlated to concentration.
Freezing Point vs. Vapor Pressure
There are osmometers that measure concentration by measuring vapor pressure. Vapor pressure osmometers may miss certain volatiles that are in the solution, such as CO2, ammonia and alcohol. Using a freezing point osmometer provides the most accurate and reliable results for many applications.
