本文采用拉曼光谱方法研究抗疲劳类保健品中非法添加化学药物的快速筛查方法.该方法结合拉曼光谱初筛、光谱叠加分析和增强拉曼光谱以获取样品的特征拉曼信息,通过分析样品和化学药物的拉曼信息的匹配程度,判断抗疲劳类保健品中是否非法添加了化学药物.采用这种方法对北京公安在市场上抽样送检的上百种保健品进行了测试,检测的准确性大于95％,这表明拉曼光谱方法可用于快速筛查抗疲劳类保健品中是否非法添加药物.

本文考察便携式拉曼光谱仪对毒品和易制毒化学品的检测识别能力,主要是利用RT3000便携式拉曼光谱仪对甲基安非他命、安眠酮等10种毒品进行测试,以及对黄樟脑、甲苯等10种易制毒化学品进行测试,同时测定白糖、淀粉等白色安全粉末的拉曼谱图.利用专门的建库软件建立以上标准物质的拉曼谱图库,并考察其识别能力.结果显示:此10种毒品和10种易制毒化学品都具有典型的特征拉曼峰,将此毒品和易制毒化学品谱图进行建库,可以对其进行分子层面的准确识别.通过对算法识别的优化以及阈值的调节,便携式拉曼光谱仪所测安全粉末的误报率为0.便携式拉曼光谱仪具有重量轻,便于携带的功能,可为毒品和易制毒化学品的现场快速判别提供一种新的手段,具有良好的应用前景.
