在原子发射光谱中,有时采用直接粉末法摄谱。在开始燃孤过程中,试样从电极孔穴中喷跳出来,是经常遇到的现象。有的呈粉末状喷溅;有的呈细小的熔球,一个或几个熔球跳出。试样的喷跳不但会降低元素灵敏度,而且给光谱分析工作带来很大误差,因此必须加以消除。根据不同情况,采用不同方法来消除:1.一般样品(像土壤样、矿物岩石样等)加一滴蒸馏水或10%糖水,在105℃烘干,使样品粘结、压实,然后摄谱。2.对碳酸盐样品可以加一滴1:1盐酸使二氧化碳先分解,然后装样压实、摄谱。3.黄铁矿样或含大量结晶水的铝土矿样,可先在马弗炉中用500℃左右灼烧一小
In atomic emission spectroscopy, sometimes direct powder spectroscopy. In the process of starting the burning solitary, the sample jets out from the electrode hole, is a phenomenon often encountered. Some were splashed powder; some were small melt ball, one or a few ball out of the melt. The jets of the sample not only reduce the elemental sensitivity but also give a great error to the spectral analysis work and must therefore be eliminated. According to different situations, different methods are used to eliminate: 1. General samples (like soil samples, mineral rock samples, etc.) Add one drop of distilled water or 10% sugar water and dry at 105 ° C to bond, compaction, and then record. 2. The carbonate sample can be added a drop of 1: 1 hydrochloric acid so that the first decomposition of carbon dioxide, and then sample compaction, photographic. 3. Pyrite or bauxite samples containing large amounts of crystal water, the first muffle furnace with about 500 ℃ burning a small
