卡尔费休库仑法水分测定仪:用于低含水量样品分析的滴定仪

卡尔费休库仑法是测定低含水量样品水汽的理想方法(0.001 到 1%水分含量)。

我们的卡尔费休库仑法水分测定仪的测定范围可以满足您的任何要求,并通过和卡氏炉联用进行复杂样品的分析。

Volumetric and coulometric Karlf Fischer titrator for water content determination with operator

主要特点:

  • 测定含水量从0.001到1%的痕量水分
  • 满足不同需求:根据需求可选择单机版或电脑控制版
  • 可通过配置卡氏炉进行复杂样品分析
  • 可选有隔膜和无隔膜发生电极
  • 符合21 CFR Part 11法规要求

卡尔费休库仑法水分测定仪的样品前处理和自动化

对于困难样品,如固体样品或者难溶样品,您可以选择卡氏炉的方法。该方法的原理是使样品在炉子里受热指导水分被释放出来,通过干燥载气将水汽传送到滴定池中进行测量。


我们提供既手动单一样品位的炉子,也提供全自动带样品盘的炉子以增加样品通量。
