Multicomponent Determination of Chlorinated Hydrocarbons Using a Reaction-Based Chemical Sensor. 3. Medium-Rank Second-Order Calibration with Restricted Tucker Models

Abstract

The calibration of a chemical sensor for chlorinated hydrocarbon analytes based on the Fujiwara reaction is described. This sensor generates a particular type of data: medium-rank second-order data. With this type of data it is possible to calibrate the sensor in such a way that quantitation for the analytes in the presence of unknown interferents is possible. The calibration method developed is a new approach based on so-called restricted Tucker models that utilize all available chemical information
