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.

DOSY NMR 测量的校准转移程序：肝素制剂的分子量示例

校准转移通常用于在不同光谱仪或其他条件下获得的光谱。本文报告了一种基于偏最小二乘法 (PLS) 回归的高分辨率核磁共振 (NMR) 光谱仪之间二维扩散有序光谱 (DOSY) 测量的多变量传递方法。作为之前公布的预测肝素分子量的定量模型的测试系统，使用了低分子量肝素（LMWH）。
