研究了便携式血糖仪(PGM)在非糖物质检测方面的应用。基于便携式血糖仪对烟酰胺腺嘌呤二核苷酸(NADH)具有剂量依赖性反应构建酶促反应,提出采用PGM实现对乙醇含量的便携式定量检测。在最佳的检测条件下,当乙醇的体积分数在3%~100%范围内变化时,PGM读数与乙醇含量之间呈现良好的线性关系,线性方程为y=0.70125+0.02148V,相关系数(R2)为0.97351,检出限为3%。 The application of portable glucose meter (PGM) in non-sugar substances testing was studied. A portable glucose meter was used to construct an enzymatic reaction to nicotinamide adenine dinucleotide (NADH) in a dose-dependent manner. A portable quantitative detection of ethanol content using PGM was proposed. Under the best detection conditions, when the volume fraction of ethanol varied from 3% to 100%, there was a good linear relationship between the PGM reading and the ethanol content, the linear equation was y = 0.70125 + 0.02148V, the correlation coefficient R2) was 0.97351, the detection limit was 3%.
