不挥发物含量的快速准确测定法

Fast and Accurate Determination of Non-Volatile Matter Content

提出了一种快速准确测定不挥发物含量的方法,其实质是采用载玻片,使样品在载玻片上形成薄而均匀的膜,加快挥发物的挥发。该方法降低了烘烤温度和烘烤时间,不但提高了工作效率,还减少了烘烤中因发生化学反应而导致小分子释放,提高了测定准确性。

This article has proposed a fast and accurate measuring method for non -vola- tile - matter content. Its essence is to use glass slide, on which samples can form a thin and u- niform film and thus accelerate the evaporation of volatile matter. Low heating temperature and short heating time not only improve the work efficiency, but also reduce the loss of small molecules caused by chemical reaction, and improve the measurement accuracy.
