Calibration transfer is commonly used for spectra obtained on different spectrometers or other conditions. This paper reports a multivariate transfer approach for 2D diffusion‐ordered spectroscopy (DOSY) measurements among high‐resolution nuclear magnetic resonance (NMR) spectrometers on the basis of partial least squares (PLS) regression. As the test system previously published quantitative model to predict molecular weight of heparin, low molecular weight heparin (LMWH) was used.
