Digital image analysis was applied to the products of simple colorimetric [corrected] tests for amphetamine and methylamphetamine. Adobe Photoshop software was used for colour analysis to obtain analytical data in the form of a Red Green Blue (RGB) value. Calibration curves were developed for each compound and a number of illicit amphetamine samples were analyzed to demonstrate the application of the technique. A wide linear range and low detection limit for both drugs under test facilitated the application to illicit samples. Good agreement with gas chromatographic quantification results was obtained for the illicit samples analyzed by this method. The results show great potential for use as a semi-quantitative field test for illicit drug compounds.
数字图像分析应用于安非他命和甲基安非他命的简单比色测试产品。使用 Adobe Photoshop 软件进行颜色分析，以获取 RGB 值形式的分析数据。为每个化合物开发了校准曲线，并分析了一些非法安非他命样本，以证明该技术的应用。对于测试的两种药物，该技术具有较宽的线性范围和较低的检测限，便于应用于非法样本。通过该方法分析的非法样本与气相色谱定量结果吻合良好。结果表明，该方法具有作为非法药物化合物现场半定量测试的巨大潜力。
