毛发样品分析前的样品处理,多系采用干化法和湿化法。用这两种方法处理样品,因操作步骤多,手续繁杂,引起的系统误差较大。因此回收率低,重现性差,结果不准。特别是对微量元素分析处理的样品引起的误差更大。 我们根据铂金丝能耐高温的原理,在灯工的协助下,自行设计研制出了“毛发作品直接燃烧处理装置”。现将该装置的制作方法和使用方 Sample preparation prior to analysis of hair samples was performed using dry and wet methods. The use of these two methods to process samples, due to many operating procedures, complicated procedures, caused by systematic errors. Therefore, the recovery rate is low, the reproducibility is poor, and the results are not accurate. In particular, samples that are processed for trace element analysis cause greater errors. Based on the principle of platinum wire resistance to high temperature, we have designed and developed a “direct working device for hair works” with the assistance of a lampmaker. The production method and the use of the device are now
