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.
