借助于火花源质谱内标法,分析头发中30种微量元素。论证一种浓度比匹配法,用以鉴别同人头发和观察不同人头发的总体差异性。理论预期与实验结果相符合。
With the help of spark source mass spectrometry, 30 kinds of trace elements in hair were analyzed. Demonstrate a concentration ratio matching method to identify fellow hair and observe the overall differences in different human hair. The theoretical expectation is consistent with the experimental results.
