1·At the preparation period adopted a method combined evaporation to dryness by water bath and microwave ashing which mostly reduced the losing of metals.
在预处理过程中采用水浴蒸干和微波灰化相结合的方法，大大减少了金属元素的损失。
2·The ashing and dissolution procedure for the plastic scintillator sample preparation was established.
建立了样品的灰化、溶解程序，并对质谱条件进行了探索。
3·A large number of experiments show that the analytical results of gold are greatly interfered by the ashing temperature and the decomposition form of plant sample.
通过大量试验表明，植物样品的灰化温度和分解方式对金的分析结果影响很大。
4·Owing to reducing the drying sta -ge and omitting the ashing stage, each cycle time will be reduced about 40%. precision results can be obtained with this method.
由于缩短了干燥时间，取消灰化阶段，使每次测定时间缩短约40%，达到快速、准确的分析结果。
