725型ICP-AES和5110型ICP-AES的操作性能及在红土镍矿分析中的应用比较
|
摘要
比较了725型ICP-AES和5110型ICP-AES的进样系统中雾化器,雾化室的操作和性能,和各自采用的矩管、观测方式和检测系统的区别,以及两者在红土镍矿元素分析测定的性能表现,5110型ICP-AES比725型ICP-AES表现出更高的精确度和更好的准确度,但是其进样系统对样品溶液的前处理要求很高,且在使用过程中,容易发生堵塞的情况,清理堵塞成为工作中的一部分,从而影响分析测定工作的连续进行;而725型ICP-AES采用的V槽式雾化器和配套的Sturman雾化室,在分析过程中,对样品溶液的前处理要求简单,能连续高效的工作,性能表现稳定,能更好的满足对红土镍矿元素分析测定的要求。
The Comparison between 725ICP-AES and 5110ICP-AES on operation performance and application on laterite analysis are discussed below. The difference on sample introduction system, including the nebulizer and spray chamber are compared, as well as the difference on torch, observation way and detection system are also detailed in this write-up. The application of the laterite analysis using the two different model of the instrument are also discussed in full detail. Both of the instrument can be used for the laterite analysis. However, the 5110ICP-AES showed higher precision and better accuracy compared with 725ICP-AES on the performance of determining the elements of interests in laterite analysis. On the other hand, it has a problem of igniting the plasma successfully at once. A stronger exhaust system is needed for heat removal due to the greater heat produced. it also has a high demand of pretreatment of sample solution and is easy to jam during work process. Also clearing the jams become part of the work,thus hinder the normal analysis work. While 725ICP-AES have simple requirements for the pretreatment of sample solution with adoption of the v-nebulizer and Sturman chamber, and showed stable performance with high efficiency, which can better meet the requirements for laterite analysis.
