水分的测定方法较多,卡尔·费休库仑法微量水分测定仪因其操作简单、准确度较高、测定速度快等优点,得到广泛应用。但此测定过程受很多因素的影响,如仪器电极、卡尔·费休试剂、样品性质、测量环境等,考虑不周或选择不当,都会使滴定结果不准确。一、影响因素1.电极的影响卡氏滴定是通过电极传输的信号判定反应终点, Determination of water more, Karl Fischer Coulometric trace moisture analyzer because of its simple, high accuracy, fast determination, etc., are widely used. However, the determination process is affected by many factors, such as the instrument electrode, Karl Fischer reagent, sample properties, measurement environment, etc., which may make the titration inaccurate due to poor or improper selection. First, the influencing factors 1. The influence of the electrode Karl Fischer titration is the signal transmitted by the electrode to determine the reaction end point,
