Applies CPU microprocessor and PID control technique, large screen Chinese display, and menu operation
Heating with double helix silicon carbide rod; temperature measured with platinum-rhodium thermocouple
Up to 4 samples can be fused simultaneously (maximum 6 samples if required by user)
Up to 10 customized heating programs can be preset; within the programs, the heating process, the temperature increase speed, the final temperature, the shaking time, shaking amplitude, and shaking speed of the crucible stool, the cooling time, whether to use fans, the air flow, and so on, all can be preset.
Automatic control in all the process except for the filling of the fusion sample, enabling the sameness and homogeneity of the sample; all samples are uniformly the same except for the differences in composition
The bracket of the crucible and the mould are made of high temperature alloy, which guarantees no chemical reaction in high temperature
Chain wheel lever structure is used in the opening device of the cover of the fusion room, trouble-free for user operation
With minimum start temperature alarm and power switch-off protection when the cover of the fusion room is open
Automatically switching off power and setting alarm for overcurrent and overheat; independent temperature measurement thermocouples are used for overheat protection and heating control; together with the heating control circuit, they can form treble protection of the system and can make the power switch-off protection for overheat more reliable.

X射线荧光分析对♀于粉末样品，目前采用直接压片法制备试样〓较为普遍，但由于粒度、矿物、偏析等效应的影响，势必带来≡分析误差，降低元素分析的精密度与准◣确度，样品制备已经成为一个主要的误差因素。玻璃←熔融法制成的试样能消除试样的粒度、矿物、偏析等效应，同时也可降低样品元素间的吸收和增强效应，会明显提高分析的精度和准确度。对于ICP、AA和湿法化学分析手段，对于难溶样№品，熔融方法同样是一种非常完美的制样手段。
多年来国内所采用的熔融设备均依赖进口，价格非常昂↓贵，针对这种局╱面，本公司科研人员于2002年开发完成了填补国内空白的DY501型√电热熔融设备。它吸取了当今国』际市场上同类制样设备的优点，其主要性能达到甚至超过国外同类产品。由于其优异★的性能和合理的价格，定将取代『进口产品，并使原来由于经济原因暂不用熔融设备的用户也能使用它。DY501型电热熔融∩设备的推出，定将迅速Ψ 普及熔融制样法，从而提高我国◤分析界制样的水平，为各行各业带来巨大的经济效益。
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.

INTRODUCTION
上海宇索电子科技有限公司是由长期致力于X荧〓光分析仪销售服务和研究开发的技术↓人员合资成立的一家高科技企业。公司的创办者在长期的X荧光分析仪的销售服务和研究开发中深切地体会到样品制备对荧光分析的重要性，而最好的样品制备方法就是玻璃熔融法，但当时国内●所采用的熔融设备均依赖进口，价格又非常昂贵，所以成立了本☉公司。
本公司在2002年成立后的短短一年时间里，就开发完成了填补国内空白的DY501型电热熔融设备。至2005年，DY501型电热熔融设备的用户已达近百家，并受到用户的一致好评。公司现有科技人员多ξ 名，其中高级工程师3名，博士1名，现正研究开发卐DY511型全自动电热熔融设备和DY521型全自动ω单头实验室用小型电热熔融设备，并将于2006年中推向市◆场。
本公司是〗样品熔融的专家，分析的好帮手。
Shanghai Yusuo Electronic S&T Co. Ltd. is a high technology enterprise established by the experienced people who focus on the sales, service and research of X-Ray analysis instrument many years. As the bead fusion is widely recognized as valuable means in X-Ray analysis, which can improve the reliability of the analysis results, but in China all the fusion machine has to imported, which very expensive and response time of service is very long. To provide local China solution, Shanghai Yusuo Electronic S&T Co., Ltd was setup on 2002.
One year after the 2002, the company introduced DY501 electroheat fusion machine. Till now, there are around hundred systems using in China, which make DY501 a very popular fusion machine. Now the company has many technical developing persons, three of them are senior engineers and one doctor. Now the new model DY511 fully automatic electroheat fusion machine and DY521 fully automatic mini electroheat fusion machine is under developing, and will introduce in the mid of 2006.
