簡介(jie)
X射線(xian)熒(ying)光分析(xi)對(dui)于(yu)粉(fen)末樣品，目前采用(yong)直接(jie)壓片法(fa)制(zhi)備試(shi)樣較為普遍，但由(you)于(yu)粒度(du)(du)、礦(kuang)物、偏析(xi)等(deng)效(xiao)應的(de)(de)影響(xiang)，勢必帶來(lai)分析(xi)誤差，降(jiang)低(di)(di)元素分析(xi)的(de)(de)精(jing)密度(du)(du)與準確度(du)(du)，樣品制(zhi)備已經成為一(yi)個主要的(de)(de)誤差因素。玻璃熔融法(fa)制(zhi)成的(de)(de)試(shi)樣能(neng)消(xiao)除(chu)試(shi)樣的(de)(de)粒度(du)(du)、礦(kuang)物、偏析(xi)等(deng)效(xiao)應，同時也可降(jiang)低(di)(di)樣品元素間的(de)(de)吸收和增強效(xiao)應，會明顯(xian)提高分析(xi)的(de)(de)精(jing)度(du)(du)和準確度(du)(du)。對(dui)于(yu)ICP、AA和濕法化學分析手段，對(dui)于難溶樣(yang)品，熔融方法同樣(yang)是一種(zhong)非常(chang)完美(mei)的制樣(yang)手段。
多年來國內所采用的熔融設備均依賴進口，價格非常昂貴，針對(dui)這種局(ju)面(mian)，本(ben)公司科研人員(yuan)于2002年開發(fa)完成了填補國(guo)內空白的DY501型電熱熔融設(she)備(bei)。它吸取(qu)(qu)了當今國際市場上同(tong)類(lei)制(zhi)樣設備的優點，其(qi)主要性能達到(dao)甚(shen)至超過(guo)國外同(tong)類(lei)產品(pin)。由(you)于其(qi)優異的性能和合理(li)的價(jia)格，定將取(qu)(qu)代(dai)進(jin)口(kou)產品(pin)，并使原(yuan)來由(you)于經濟(ji)原(yuan)因暫不用(yong)熔融設備的用(yong)戶也能使用(yong)它。DY501型電熱(re)熔融設(she)備的推出，定(ding)將迅(xun)速普及熔融(rong)制樣法，從而提高我(wo)國分析界制樣的水平，為(wei)各(ge)行各(ge)業帶來(lai)巨大的經濟(ji)效益。
Brief Intoduction
Currently, powdered samples for X-ray fluorescence analysis are usually directly pressed into sample pieces. But that kind of sampling has become a major error factor impacting the precision and accuracy of the element analysis due to the granularity effect, mineral effect and segregation effect of the sample pieces. The bead fusion method can eliminate the granularity, mineral and segregation effects of the samples, and can reduce the absorption and enhancement effects between the elements in the sample, and hence evidently increase the precision and accuracy of the analysis. This bead fusion method is a perfect sampling method for ICP, AA, as well as for indissolvable samples in wet chemical analysis.
For many years, the fusion machine used in China were all imported from abroad at very high price. To fill up that gap in Chinese science and technology, the research and development personnel in our company developed the DY501 Electroheat Fusion Machine in the year 2002. This fusion machine absorbed the advantages of all the fusion machine of the same kind in the international markets, with key properties up to or even better than those of the overseas products. With its excellent performance and reasonable price, it will take the place of the imported products and can be affordable for the users which are currently not using fusion units just because of economic reasons. The popularization of the DY501 Electroheat Fusion Machine will rapidly promote the bead fusion method in China and hence improve the sampling quality of the element analysis, which can bring tremendous economic benefit for every industry or trade.
