电子天平如何测量固体密度

Update time:2020-06-05 14:34:28The number of clicks:11387TimesSize:T|T


电子密度天平


1.辅助液体的表面张力


液体粘附到挂篮上会使表面质量增加3mg。当在固体的两次称量中(空气和辅助液体中)下挂篮浸入辅助液体中时,辅助液体表面张力所引起的量增大的影响可以忽略不计。因为电子天平在每次测量前都会去皮。为了降低气泡的影响和确保大的可能精度,可以使用几滴润湿剂(不提供)并添加到辅助液体中。

2.温度

固体一般对温度变动不是特别敏感,但测量密度过程中利用辅助液体工作时,须考虑温度对液体的较大影响。一般会以0.1℃到1℃的数量级引起密度的变化。此时会影响到测量结果中的第三小数位的变化。建议在固体密度测量过程中始终考虑到辅助液体的温度。
