Several methods based on multivariate statistical analysis such as CPA matrix, principal component analysis (PCA), target factor analysis (TFA), ordinary and adaptive Kalman filtering (OKF and AKF), etc. have been applied for simultaneous determination of the multicomponent systems, e. g. a mixture sample composed of Ti,Mo, W and Sn, With phenylfluorone-CTMAB chromogenic system. Comparison of the methods is also give-
