The electrochemical quantification of new psychoactive substances 2,5-dimethoxy-N-(2-methoxybenzyl)phenethylamines, commonly described as NBOMes and their correlates, 2,5-dimethoxy phenethylamine structures, also known as 2C family compounds, in seized blotting paper is presented using square-wave voltammetry (SWV) on a boron-doped diamond (BDD) electrode. Under optimized experimental conditions, linear analytical curves were obtained in the range from 1 to 555 μmol L⁻¹ for three NBOMes and 2C–B with detection limit values between 0.1 and 0.3 μmol L⁻¹ (corresponding to 0.03 and 0.10 μg mL⁻¹) and a repeatability of around 1% (n = 10) for the detection of all analytes. The accuracy of the proposed method was evaluated using seized samples, which were also analyzed by quadrupole time of flight liquid chromatography-mass spectrometry (QTOF LC-MS), with perfect agreement, and free from interference of the sample matrix (recovery values between 98 and 110%).

掺硼金刚石电极上方波伏安法电化学检测吸墨纸中的NBOMes和其他新型精神活性物质

新的精神活性物质2,5-二甲氧基-N-（2-甲氧基苄基）苯乙胺的电化学定量，通常称为NBOMes及其相关物质，在检出的吸墨纸中为2,5-二甲氧基苯乙胺结构，也称为2C族化合物。在掺硼金刚石（BDD）电极上使用方波伏安法（SWV）进行了研究。在优化的实验条件下，对于三个NBOM和2C–B ，线性分析曲线的取值范围为1至555μmolL ^-1，检测极限值为0.1至0.3μmolL ^-1（对应于0.03至0.10μgmL ^-1），重复性约为1％（n= 10）用于检测所有分析物。使用检出的样品评估了所提出方法的准确性，并通过四极杆飞行时间液相色谱-质谱（QTOF LC-MS）分析了样品，并取得了完全一致的结果，并且没有样品基质的干扰（回收率介于98和98之间）。和110％）。
