摘要：

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. (C) 2000 Elsevier Science B.V. All rights reserved.
