Abstract
An osmometer probe comprises a cage which carries abrasive material and encloses a temperature sensor. In use, the probe is placed in a super-cooled solution and the abrasive material detaches particles of the container which initiate crystallization of the solution, the temperature on crystallization being measured by means of the temperature sensor.
Claims6
A device for determining the concentration of particles of a solute in a solvent, comprising a temperature-sensitive probe provided with abrasive or cutting means for detaching particles from the interior of a container for the solution.
A method of determining the concentration of particles of a solute in a solvent, comprising the steps of super-cooling the solution formed by the solute and solvent and containing the super-cooled solution in a container, inserting into the solution in the container a temperature-sensitive probe provided with abrasive or cutting means, detaching particles from the interior of the container by operation of the abrasive or cutting means thereby initiating crystallisation of the super-cooled solution about the said particles acting as nuclei, and measuring the temperature of the crystallising solution, the said temperature being a measure of the said concentration of particles.
