ABSTRACT:
A method and apparatus is provided for detecting an impurity in a sample where an index can be calculated to assess purity in the presence of n major components with signal averaging or noise-filtering automatically built-in. The method and apparatus can be applied to liquid chromatography impurity detection using UV-VIS spectrophotometry based on robust matrix algebra representing the entire spectral space generated by the sample.
