我厂氢氟酸分析,过去一直是用感量1 mg的分析天平称量,试料用带盖黄金坩埚盛装,由于分析次数频繁’(每80~40分钟一次),每年仅用于氟酸分析就要消耗千分之一天平一台。且不安全,分析人员稍不注意,就有被酸烧的危险。因而,改革氢氟酸的称量方法,是分析人员的迫切愿望。在兄弟单位的协助下,我们用聚乙烯原子笔杆拉成相当于0.5克或1克氟酸的吸嘴,再套进半截有机玻璃移液管(胖肚以上部分)内,上套滴管橡皮头,
Hydrofluoric acid analysis of our factory, in the past has been weighed 1kg with a sense of analytical balance, the sample was covered with a gold crucible, due to frequent analysis’ (every 80 to 40 minutes), only for the annual fluoride acid Analysis will consume one thousandth of a balance. And unsafe, analysts little attention, there is danger of being sour. Therefore, the reform of hydrofluoric acid weighing method is the urgent desire of analysts. With the assistance of our brothers, we use a polyethylene atomic pen to pull a nozzle equivalent to 0.5g or 1g of fluoric acid, then put it into a half plexiglass pipette (above the fat belly) head,
