Calibration transfer from a scanning near-IR spectrophotometer to a FT-near-IR spectrophotometer

Abstract A principal component regression calibration model developed on a scanning near-IR spectrophotometer (with a standard cuvette) was transferred to a Fourier transform near-IR spectrophotometer (with a fiber-optic probe) for the determination of NaCl in aqueous solutions by using piecewise direct standardization method. Only two transfer samples were needed in obtaining a good calibration transfer. Standard error of prediction obtainable from the calibration transfer was 0.034 M, compared to 0.012 M produced by the full set recalibration for NaCl in the concentration range of 0–5 M.
