Globally, the number of drug users and the proportion of the drug using population has increased from 210 million in 2009 to 269 million in 2019. Several studies suggest that music festival attendees are more likely to abuse illicit substances and have a high-risk profile. Consequently, it is crucial to develop robust field drug analysis methods that facilitate harm reduction and drug monitoring. The work presented in this report aimed at developing and validating qualitative analytical methods for 3,4-methylenedioxymethamphetamine, 4-bromo-2,5-dimethoxyphenethylamine (2C-B), ketamine and N-ethylpentylone on two portable gas chromatography–mass spectrometry (GC–MS) systems: Griffin G510 (Teledyne FLIR, West Lafayette, IN) and Torion T-9 (PerkinElmer, Shelton, CT). The diagnostic ability of the mobile GC–MS units was assessed on 200 samples in total, seized at two large summer music festivals in the United Kingdom. The method validation process included selectivity/specificity, limit of identification, carry-over, ruggedness/robustness, and inter- and intra-day precision (repeatability and reproducibility). The Griffin G510 demonstrated a limit of identification from 1 mg/mL for 2C-B to 0.063 mg/mL for ketamine and good ruggedness and precision results. The precision for 2C-B using the Torion T-9 was poorer than for the Griffin G510, but equivalent for the other compounds tested. Correct identifications (versus benchtop GC–MS) for the two festivals were 85%–86% and 74%–83% for the Griffin G510 and the Torion T-9, respectively. The two portable instruments were able to adequately cover current on-site drug-testing analytical gaps and proved to be a powerful addition to the on-site drug analysis techniques.

使用两台便携式气相色谱-质谱 (GC-MS) 仪器分析在英国两个主要夏季音乐节上从特赦箱中查获的毒品



在全球范围内,吸毒者人数和吸毒人口比例已从 2009 年的 2.1 亿增加到 2019 年的 2.69 亿。多项研究表明,音乐节参加者更有可能滥用非法药物,且具有高风险特征。因此,开发强大的现场药物分析方法以促进减少危害和药物监测至关重要。本报告中介绍的工作旨在开发和验证两种便携式气相色谱-质谱仪 (2C-B)、3,4-亚甲二氧基甲基苯丙胺、4-溴-2,5-二甲氧基苯乙胺 (2C-B)、氯胺酮和N-乙基戊酮的定性分析方法( GC-MS)系统:Griffin G510(Teledyne FLIR,西拉斐特,印第安纳州)和 Torion T-9(PerkinElmer,谢尔顿,康涅狄格州)。移动 GC-MS 装置的诊断能力对在英国两个大型夏季音乐节上采集的总共 200 个样本进行了评估。方法验证过程包括选择性/特异性、识别限度、残留、耐用性/稳健性以及日间和日内精度(重复性和再现性)。 Griffin G510 的识别限从 2C-B 的 1 mg/mL 到氯胺酮的 0.063 mg/mL,并且具有良好的耐用性和精确度结果。使用 Torion T-9 的 2C-B 精度比 Griffin G510 差,但与测试的其他化合物相当。 Griffin G510 和 Torion T-9 的两个节日的正确识别率(与台式 GC-MS 相比)分别为 85%–86% 和 74%–83%。这两种便携式仪器能够充分弥补当前现场药物测试分析的空白,并被证明是对现场药物分析技术的有力补充。
