Interview with Till Myrach conducted by James Ives, MPsych Please give an overview of osmometry in general. Osmometry is a method to determine a sample ́s osmolality. This is the total number of osmotically active particles solved in a solution.
These particles influence the colligative properties of the solution, which include the boiling and freezing point but also the vapor pressure for instance. © Shutterstock.com / Besjunior While the first parameter is elevated with an increasing number of particles in a solution the other two are lowered.
The fascinating point about osmolality is, that it depends on the number of solute particles but not on their chemical nature. Therefore, it can be considered as a value representing total concentration of solutes. A field of application for example is the quality control of isotonic beverages.
What measurement principle is used in Knauer’s K-7400S semi-micro osmometer to determine the osmolality of sample liquids? Our osmometer is based on the principle of freezing point osmometry. As mentioned the freezing point of a solution is depressed with an increasing number of solute particles and this change is precisely determined by the K-7400S.
