Coulometric Karl Fischer titrators

Stand-alone or computer-controlled coulometers for the determination of low water content or moisture content (0.001 to 1%) by coulometric titration.


Highlights

Coulometric Karl Fischer titrators are ideal to determine low moisture and water contents in liquid, solid, or gaseous samples (0.001 to 1% water content). Our range of coulometers covers any requirements and can be combined with the Karl Fischer oven method for the analysis of difficult samples.

  • Accurate and reliable determination of trace-level water contents in the range of 0.001 to 1 %
  • Various coulometer versions available, e.g., stand-alone or computer-controlled
  • Difficult samples can easily be analyzed with the oven method
  • Compliance with FDA Regulation 21 CFR Part 11 and EudraLex, Volume 4, Annex 11

Sample preparation and automation for coulometric KF titration

917 Coulometer and 885 Compact Oven Sample Changer

For difficult samples, e.g., solid samples or samples that do not readily dissolve, you may apply the KF oven method. In this method, the sample is heated in an oven until the water is released, and the water vapor is transferred to the titration vessel for measurement.

We offer both manual ovens and automated sample changers with integrated ovens for increased sample throughput.
