Abstract
The composition distribution of a sample in solution is determined by basing the calculation of the composition distribution on intermittent measurements of the concentration of sample remaining in solution while precipitating the sample from the solution. An apparatus for determining the composition distribution of the sample has a sample solution vessel, a temperature control for raising and lowering the temperature of a solvent within the vessel, and a device for intermittently measuring concentration of sample in solution in the vessel.
Claims11
An analytical method for analysis of precipitation of a soluble sample comprising the steps of:
- (A) providing a sample in solution;
- (B) precipitating the sample from the solution while intermittently measuring the concentration of sample remaining in the solution;
- and
- (C) based on the results of step (B), calculating the composition distribution of the sample.
An analytical method for analysis of precipitation of a plurality of soluble samples comprising the steps of:
- (A) providing said plurality of samples in separate solutions;
- (B) precipitating said samples from said solutions while intermittently and sequentially measuring the concentration of sample remaining in each solution;
- and
- (C) based on the results of step (B), calculating the composition of each sample.
An apparatus for analyzing the composition distribution of a soluble sample, said apparatus having:
- a sample vessel;
- temperature control means for raising and lowering the temperature of a solvent within said vessel;
- and
- solution concentration detection means for intermittently measuring concentration of sample remaining in a solution within said vessel.
