Weisz环炉技术的出现标志着点滴分析步入了一个新的纪元。它的优点是设备简单,操作迅速,在一滴溶液中可以对若干种离子或化合物进行分离、检出或作半定量分析;若与其他分析方法联用,又可以测定物质的痕量组分。对此,Weisz曾于1961年写了一本小册子,介绍了这一方法并总结了1954—1961年间有关这方面的发展情况。最近几年来,介绍环炉技术的文章为数不少;而该法本身又有了新的内容。本文拟就其新进展作一评述。
The emergence of the Weisz loop furnace technology marks a new era in drip analysis. Its advantage is simple equipment, rapid operation, in a drop of solution can be a number of ions or compounds were isolated, detected or semi-quantitative analysis; if combined with other analytical methods, but also to determine the trace components of the material. In response, Weisz wrote a pamphlet in 1961, introducing the method and summarizing developments in this area during 1954-1961. In recent years there have been many articles on ring furnace technology, and the law itself has new content. This article intends to make a comment on its new progress.
