伦敦King's College的研究人员与Northumbria University合作，研发了一种能够检测自制爆炸物，并能帮助法庭科学家追踪爆炸物来源的新方法。该方法使用了离子色谱法-高分辨率质谱筛选法，并发表于Analytica Chimica Acta. 

自制炸药经常用于许多不同的犯罪活动。 也常用于抢劫自动取款机。传统上，对提交的样本进行检测和追踪是非常困难的。

该小组成功地利用新方法，由汗液，分析出爆炸物材料的源头制造商。利用该方法，还能通过分析枪击残留物去追踪所用枪支类型。

King's College的Leon Barron博士表示，该方法能够呈现给研究人员更多炸弹组成之外的信息。能够同时检测出数千种化合物，也就意味着能够在未来有新类型炸弹出现的情况下，提供犯罪者的相关信息。

Researchers at King's College London, in collaboration with Northumbria University, have developed a new way of detecting homemade explosives which will help forensic scientists trace where it came from. The approach uses ion chromatography - high resolution mass spectrometry, published today in Analytica Chimica Acta. 

Homemade explosives are frequently used in a number of different crimes. They are also used in ATM robberies. They have traditionally been very challenging to detect and trace in samples submitted for forensic analysis.

The team successfully went on to use the new approach to interpret the time since explosives materials were handled by the original maker, analyzing sweat. They were also able to analyze gunshot residue to trace the type of ammunition used.
