Unified Approach to the Evaluation of Analytical Data in Control Applications

Abstract

A new problem representation for evaluation of analytical data is offered. The data considered are generated by multicomponent composition analyzers such as ordinary spectrometers, mass spectrometers, and chromatometers. Each instrument defines a transform that relates the output of the instrument to its input. In terms of the instrument transform, we discuss the use of digital computers to improve the efficiency of interpretation of raw data. Special reference is made to optical direct-reading emission spectrometers in process-control applications. It is believed that the concept of the instrument transform will stimulate creative contributions in the analyst's collaboration with computers.
