微量定量环测量装置和测量方法的研究

Research on measurement of micro quantitative loop

设计了一种气液双路自动切换装置,研究了微量定量环体积的测试方法。结果显示,气液双路自动切换装置能准确将定量环中纯净水切换出来,再利用智能电子天平称重法自动计算定量环定量体积,测定结果与理论值基本一致。

A gas-liquid two-way automatic switching device was designed.Based on the device,the volume of micro loop could be automatically calculated by using intelligent electronic weighing scales method.The result was consistent with the theoretical value.
