Multiple univariate symbolic control chart for internal quality control of analytical data

Abstract

A symbolic chart showing simultaneously the results of a large number of analytes has been devised for analytical internal quality control. The primary purpose is to provide a rapid visual appraisal as a pseudomultivariate method. The chart can be readily produced and can be modified to emphasise particular aspects.
