求翻译:The stopper was removed, and the nitric acid was evaporated to obtain a volume of approximately 5 mL. The sample was cooled, and 5 mL of concentrated perchloric acid was added. Again,a Teflon stopper with a 30-cm-long glass tube was used, and the sample was digested at 220 ◦ C for 30 min; the nitric acid was volatilize是什么意思? 待解决

止动器已被删除,而硝酸蒸发获得批量约为5ml。 该样本是冷却,5毫升的集中添加了(d)木箱。 再次,一个聚四氟乙烯止动器与一个30厘米长的玻璃管,该样本是在消化220◦C30分钟;硝酸volatilized在这一阶段。

去除了停止者,并且硝酸被蒸发得到大约5机器语言的容量。 冷却了样品,并且5机器语言被集中的高氯酸增加了。 再次,用一个30 cm长的玻璃管使用了聚四氟乙烯停止者,并且样品被消化了在220 ◦ C 30分钟; 在这个阶段期间,硝酸被挥发了。
