簡介

X射線熒光分析對于粉末樣品，目前采用直接壓片法制備試樣較為普遍，但由于粒度、礦物、偏析等效應的影響，勢必帶來分析誤差，降低元素分析的精密度與準確度，樣品制備已經成為一個主要的誤差因素。玻璃熔融法制成的試樣能消除試樣的粒度、礦物、偏析等效應，同時也可降低樣品元素間的吸收和增強效應，會明顯提高分析的精度和準確度。對于ICP、AA和濕法化學分析手段，對于難溶樣品，熔融方法同樣是一種非常的制樣手段。

多年來國內所采用的熔融設備均依賴進口，價格非常昂貴，針對這種局面，本公司科研人的DY501型電熱熔融設備。它吸取了當今市場上同類制樣設備的優點，其主要性能達到甚至超過國外同類產品。由于其優異的性能和合理的價格，定將取代進口產品，并使原來由于經濟原因暫不用熔融設備的用戶也能使用它。DY501型電熱熔融設備的推出，定將迅速普及熔融制樣法，從而提高我國分析界制樣的水平，為各行各業帶來巨大的經濟效益。

Brief Intoduction

Currently, powdered samples for X-ray fluorescenceanalysis are usually directly pressed into sample pieces. But that kind ofsampling has become a major error factor impacting the precision and accuracyof the element analysis due to the granularity effect, mineral effect andsegregation effect of the sample pieces. The bead fusion method can eliminatethe granularity, mineral and segregation effects of the samples, and can reducethe absorption and enhancement effects between the elements in the sample, andhence evidently increase the precision and accuracy of the analysis. This beadfusion method is a perfect sampling method for ICP, AA, as well as forindissolvable samples in wet chemical analysis.

For many years, the fusion machine used in Chinawere all imported from abroad at very high price. To fill up that gap in Chinesescience and technology, the research and development personnel in our companydeveloped the DY501 Electroheat Fusion Machine in the year 2002. This fusionmachine absorbed the advantages of all the fusion machine of the same kind inthe international markets, with key properties up to or even better than thoseof the overseas products. With its excellent performance and reasonable price,it will take the place of the imported products and can be affordable for theusers which are currently not using fusion units just because of economicreasons. The popularization of the DY501 Electroheat Fusion Machine willrapidly promote the bead fusion method in China and hence improve the samplingquality of the element analysis, which can bring tremendous economic benefitfor every industry or trade.
