Abstract
The present invention relates to a method of monitoring the blending of at least two blendable components to yield a mixture.
Claims10
A method of monitoring the blending of at least two blendable components with at least two of the blendable components having different peak spectra, comprising:
- a) blending the at least two components in a vessel to form a mixture;
- b) generating a sample spectrum of the mixture;
- c) measuring the area of the peak spectra of the at least two components having different peak spectra in the sample spectrum;
- d) comparing at least one ratio of the areas of the peak spectra of the at least two components having the different peak spectra of the sample spectrum with the corresponding ratio of the same components from a target spectrum of a known standard mixture, and when a predetermined match of the ratios is obtained, discontinuing the blending step;
- and
- e) optionally continuing to blend the at least two components and repeating steps (b) through (d) until a predetermined match of the ratios is obtained.
