Multicomponent Determination of Chlorinated Hydrocarbons Using a Reaction-Based Chemical Sensor. 1. Multivariate Calibration of Fujiwara Reaction Products

Multicomponent analysis for 1,1,1-trichloroethane, trichloroethylene and chloroform is demonstrated by partial least squares modeling absorbance data collected from the Fujiwara reaction of these analytes over time. Optimal calibration times are determined for each analyte dependent upon its reactio...
