自动辨别颜色滴定仪的原理与开发

The Principle and Development of Automatic Colour Discrimination Titration Instrument

目前在售的自动滴定仪很多,但终点的判断都是靠测定电压、电流。与此相反,大部分的化学滴定是用指示剂颜色变化判断终点的。这样的滴定就无法采用自动滴定的方法。本文研制了一种自动分析颜色的滴定仪,尚未见文献报道。

Lots of automatic titrators were on sell,which depended on the measurement of voltage or current.On the other hand,lots of chemical titrations used colour indicator to determine end point.These kinds of chemical titrations could not be automatic currently.A automatic colour discrimination titrator was developed that was not found in literature until now.
