光谱仪：采用光谱仪进行光谱分析中样品只需要打磨掉表面氧化皮，固体样品即可放在样品台上激发，免去了化学分析钻取试样的麻烦。对于铝及铜、锌等有色金属样品而言，可用小车床车去表面氧化皮即可。
Spectrometer: in the spectroscopic analysis, the sample only needs to be polished off the oxide skin on the surface, and the solid sample can be excited on the sample table, which avoids the trouble of drilling the sample for chemical analysis. For aluminum, copper, zinc and other non-ferrous metal samples, you can use a small lathe to remove the oxide skin on the surface.
化学法：化学法取样是原来的检测方法中最重要的环节，取样环节很容易因为取样人的波动而产生微量变化，从而影响测量结果，另外取样时间是整个测试中最长的过程。
Chemical method: chemical method sampling is the most important part of the original detection method. It is easy for the sampling part to produce micro changes due to the fluctuation of the sampling person, thus affecting the measurement results. In addition, the sampling time is the longest process in the whole test.
