There are six fundamental application areas in which the knowledge of Freezing point depression can be applied.
|If you know:||And you measure:||You can determine:||The application is:|
|The normal or original freezing point of a solution and that contamination has taken place||The freezing point of a solution||The percentage dilution or change in concentration||Concentration of body fluids or Quality Control of standards and solutions.|
|The weight of solute A and the freezing point of solvent B||The freezing point of A plus B||The volume of the container occupied by B||Measuring volumes of containers, tanks, kettles, pipettes, human body, etc.|
|The specific gravity of a solution||The freezing point of the solution||The approximate size and number of dissolved molecules.||Measuring the dialyzability of solute.|
|The freezing point of a solution at time A||The freezing point of a solution at time B||The change in number of molecules due to diastasis or other factors.If freezing point is measured over a number of known time intervals, then the rate of reaction can be measured.||Measurement of enzyme activity.|
|The type of dissolved molecule, the weight of solute, and the weight of solvent||The freezing point of the solution||The molecular weight of the solute.||Molecular weight determinations|
|The molecular weight of the dissolved solute molecule, the weight of solute, and the weight of solvent||The freezing point of the solution||The osmotic coefficient of the solute in the solvent.||Determination of water binding, activity, etc.|
Each of these six areas for freezing point determination have numerous practical applications for osmolality testing specific to an industry, process or technology. Osmolality testing is a fundamental scientific technique with virtually limitless applicability. Advanced Osmometers set the benchmark for performance, accuracy and reliability.
