随着ICP光源的广泛应用和地球化学找矿的进展,要求对数以万计的化探样品进行分析。目前采用ICP光源溶液法分析较为常见,然而试样处理比较麻烦。我们根据电弧吹样法原理,采用高频火花放电,驱动粉末试样成尘雾状,随载气引入等离子矩,开展了ICP固体粉末法的研究工作,设计制作了粉末送样装置。最近,针对这一装置存在的问题和在 With the widespread use of ICP light sources and advances in geochemical prospecting, the analysis of tens of thousands of geochemical samples is required. At present, the ICP light source solution method is more common, however, the sample processing is rather troublesome. According to the principle of arc blowing method, high-frequency spark discharge was used to drive the powder sample into a dusty mist. With the introduction of plasma gas, the ICP solid powder method was researched and a powder sampling device was designed and manufactured. Recently, there are problems with this device
