We demonstrate the potential of Raman spectroscopy to detect cocaine concealed inside transparent glass bottles containing alcoholic beverages. A clear Raman signature of cocaine with good signal-to-noise was obtained from a approximately 300 g solution of adulterated cocaine (purity 75%) in a 0.7 L authentic brown bottle of rum with 1 s acquisition time. The detection limit was estimated to be of the order of 9 g of pure cocaine per 0.7 L (approximately 0.04 moles L(-1)) with 1 s acquisition time. The technique holds great promise for the fast, non-invasive, detection of concealed illicit compounds inside beverages using portable Raman instruments, thus permitting drug trafficking to be combated more effectively.
我们展示了拉曼光谱法检测隐藏在装有酒精饮料的透明玻璃瓶内可卡因的潜力。在一个0.7升正宗棕色朗姆酒瓶中，对大约300克掺假可卡因（纯度75%）的溶液进行1秒采集时间的测量，获得了具有良好信噪比的可卡因清晰拉曼特征峰。估计检测限约为每0.7升9克纯可卡因（约0.04摩尔/升），采集时间为1秒。该技术有望利用便携式拉曼仪器快速、非侵入性地检测饮料中隐藏的非法化合物，从而更有效地打击毒品贩运。
