摘要

目的: 应用近红外光谱法建立一种逍遥丸(浓缩丸)中水分含量的快速测定方法。方法: 利用烘干法测定样品中水分含量

并以其作为参考值

运用偏最小二乘法(PLS)建立水分含量与近红外光谱之间的多元校正模型

对未知样品进行含量预测。结果: 所建水分定量分析模型的相关系数(R2)

校正均方差(RMSEC)

预测均方差(RMSEP)分别为0.953 52

0.132

0.177。结论: 方法操作简便

无污染

结果准确可靠

可用于逍遥丸(浓缩丸)中水分含量的快速测定。

Abstract

Objective: To establish a rapid analytical method for moisture in Xiaoyao pills(condensed) by near-infrared spectroscopy. Method: The near-infrared spectral data of 97 samples were collected by Nicolet 6700 NIR spectroradiometer

and the data of moisture content were obtained by oven-drying method. Then

the multivariate calibration model for moisture was established by patrical least square (PLS) with oven-drying method analysis values as reference

and predicting the moisture content of unknow samples. Result: The correlation coefficients (R2) of the quantitative calibration model for moisture was 0.953 52

the root-mean-square error of calibration (RMSEC) was 0.132

the root-mean-square error of prediction (RMSEP) was 0.177. Conclusion: The method is simple

non-polluted

accurate

which could be applied for the fast determination of moisture in Xiaoyao pills(condensed).
