A modification to window target-testing factor analysis using a Gaussian window

A procedure referred to as window target-testing factor analysis (WTTFA) was recently proposed for confirming the presence of target analytes in complex spectrochromatographic applications. In this paper, a modification to the original method is proposed which uses a Gaussian mask to adapt the window shape to that of the elution profile. It is shown that this alteration results in significant improvements in the performance of the WTTFA algorithm.
