Calibration update strategies for an array of potentiometric chemical sensors

•Calibration update methods for potentiometric sensor array compared.•Detection of copper, lead and cadmium in digested wine used as a case study.•Model expansion methods perform better than signal standardization.•Weighting, Tikhonov regularization and Joint Y-PLS produce similar results. One of th...
