| 摘 要： | 探索一种方便、快速、可靠的分析手段对于尿糖检测来说具有十分重要的意义.利用近红外光谱测试分析葡萄糖浓度为0 mg/dL-1 200 mg/dL的尿液样本,并通过偏最小二乘回归结合一阶导数光谱法构建尿糖浓度的预测模型,用于建模的光谱区域为900 nm-1 600 nm.研究表明,主成分个数为6时,训练集的线性相关系数达0.999 0,总体方均根误差为9.85 mg/dL,校验样本的总体方均根误差为26.51 mg/dL.鉴于近红外光谱技术具有方便、准确、廉价等优点,其可以为尿糖检测提供一种快速分析手段.

| Abstract: | To explore a convenient, rapid and accurate analytical method can be of great importance for the detection of glucose in urine. In this paper, near-infrared spectroscopy was adopted to measure and analyze glucose in urine samples （glucose concentration： 0 - 1 200 mg/dL） . The partial least square regression method in combination with first derivative Spectrophotometry was used for mod-eling, and the modeling spectral region is 900 - 1 600 nm. The results show that the number of principal components is 6, the correla-tion coefficient and the root-mean-square,error of the training set are 0.999 0 and 9.85 mg/dL, respectively, and the root-mean-square-error of the validation samples is found to be 26.51 mg/dL. In view of its convenience, aecuraecy and low cost, near-infrared spectros- copy may offer a potential for rapid measurement of glucose in urine. |
