Karl Fisher; Excess Drift
If you are getting excess drift > 34 ug/min there may be more than one cause and solution to remedy the error.
These solutions are general best practices for moisture testing but apply specifically to the CSC Scientific Aquapal III Titator.
Cause: Indicates Excess Moisture: (usually caused by adding sample before pressing start.
Remedy: Turn CELL off and on. Check septas for air tight seal.
Cause: Excess moisture in headspace or on walls of vessel.
Remedy: Remove vessel from clamp and SWIRL so anode solution rises along wall to absorb moisture.
Cause: Reagents depleted if more than three (3) weeks old.
Remedy: Change reagents.
We will be offering more tips on how to acquire reliable and more importantly, repeatable results from your moisture titration system.
