摘要
在X射线荧光分析中,多次使用铂金坩埚将样品熔片熔融后,铂金坩埚很难恢复熔片前的原始状态,一些常见的“铂毒”可以在几个样品制备周期内对坩埚造成破坏。文章概述常见的“毒物”及其腐蚀作用的原理,介绍减少或消除其影响的技术方法以及简单的基本预防措施,有效延长铂金坩埚使用寿命,并探讨试验过程中谨慎性不足造成严重后果的案例。
In X-ray fluorescence analysis,it is difficult for the platinum crucible to restore the original state before melting the sample melt after melting the sample melt many times.Some common"platinum poisons"can damage the crucible in several sample preparation cycles.The article outlines common"poisons"and the principles of their corrosive effects,introduces technical methods to reduce or eliminate their effects and simple basic preventive measures to effectively extend the service life of platinum crucibles,and tells cases of serious consequences caused by insufficient caution during the test process.
