DY501 Electric Heating Melting Equipment Electric Melting Equipment
Description:

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.

Features

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.
