Abstract
Abstract The combination of multivariate calibration and spectroscopic analysis technology can achieve the rapid analysis of substance. However, when the external environmental conditions such as instruments or accessories are replaced or temperature changed, the current master calibration may be “invalid”. Recalibration usually takes a lot of time and financial resources. The development of calibration transfer techniques can solve this problem well, and the adaptability and robustness of the calibration are enhanced by correcting the spectra or selecting variables, therefore it is very important for popularizing the use of calibrations. This review describes a number of new calibration transfer methods and their applications in recent years, and introduces them according to traditional transfer methods, new methods and new strategies. The applications of each method as well as both its advantages and disadvantages are evaluated.
