摘要：

Three multivariate calibration methods, partial least-squares (PLS-1 and PLS-2) and principal component regression (PCR), were applied to the simultaneous determination of cypermethrin, fenvalerate and cis- and trans-permethrin by HPLC. Several preprocessing algorithms for pretreatment of data in chemometric approaches are discussed. Mean centering and the selection of the chromatogram region to realize the calibration were found to be advantageous.
