1、检验与认证荧光熔剂熔融损失对XRF分析的影响The influence of fluorescence flux melting loss to XRF analysis韩 蔚 梅一飞 周 建(中国建材检验认证集团股份有限公司,北京 100024)摘 要:荧光熔剂在高温熔融状态下会发生熔融损失,熔剂的熔融损失包括熔剂在制备、运输、贮存等过程中吸收的水分和熔剂在高温状态下自身的挥发损失。本文通过一系列的实验,对熔剂熔融损失进行了研究,实验结果表明,熔剂在高温熔融过程中会存在一定量的熔融损失,但如在高温熔融前对熔剂进行灼烧处理,则熔剂在高温熔融过程中虽仍存
2、在熔融损失,但由于其熔融损失量基本保持恒定,因此仍可准确进行定量。关键词:荧光熔剂;高温熔融;熔融损失Abstract:Fluorescence flux at high temperatures will appear to melting loss,which including absorbing moisture in the preparation,transport, storage and other processes and itself volatilization loss at high temperature.The flu
3、x melting losses were studied by a series of experiments,and experimental results show that the flux at high temperature will occur a certain amount of melting loss,but if the flux was ignited before the high-temperature melting process,though the flux at high temperature still
4、 present melting loss,but because its melting loss remained constant, therefore it can be accurately quantified.Keywords:fluorescence flux;high-temperature melting;melting loss中图分类号:O 657.34 文献标识码:B 文章编号:1003-8965(2015)01-0001-031前 言3实验方法[1,2]X射线荧光光谱法和绝大多数仪器分析方法一样,是一种相对分析方法,它需要
