The techniques of thin-layer chromatography, gas chromatography with electron capture detection, and gas chromatography/mass spectrometry were used to analyze hand swab extracts for the presence of nitroglycerine. Both the amount of nitroglycerine transferred to the hands after handling commercial explosives and its persistence were measured. Gas chromatography-electron capture detection was found to be the most accurate and sensitive technique for making such determinations, especially if the extract was partially purified by thin-layer chromatography prior to analysis. The lowest limit of detection was 10 ng of nitroglycerine, and residues could be detected over 20 h after handling the raw explosive.
采用薄层色谱法、带电子捕获检测的气相色谱法以及气相色谱/质谱联用法，分析手部拭子提取物中是否存在硝酸甘油。测定了处理商业炸药后转移到手上的硝酸甘油量及其持久性。结果发现，气相色谱 - 电子捕获检测法是进行此类测定最准确、最灵敏的技术，尤其是在分析前提取物通过薄层色谱法进行部分纯化的情况下。最低检测限为10纳克硝酸甘油，处理未加工炸药20小时后仍可检测到残留物。
