Registered users onlyTitration results are varying, bad repeatability and accuracy
Titration results are too varied, the repeatability of a sample series is bad (> 2%), the expected results are sometimes met, sometimes not. What is the reason, how can this be improved?
Fluctuating results in volumetric Karl Fischer titration
The results in volumetric Karl Fischer titration are fluctuating – what are the reasons?
Karl Fischer solvent gets dark
What are the causes for the solution in the KF vessel getting dark, even after the first water determination?
The volumetric KF titration is unusually slow
The Karl Fischer titration appears to be slow or becomes slower from time to time. What influences the KF titration speed?
How to avoid fluctuating concentration values of KF titrants if di-sodium tartrate is used as the standard?
The concentration determination of the KF titrant is fluctuating; the concentration values are constantly out of specifications even if a new KF titrant is used?
The pH glass sensor cannot measure basic buffer values above pH 10
The pH glass sensor cannot accurately measure basic buffer values above pH 10. What are the reasons?
Too high results in pH end point titration
A pH end point titration shows repeatable results but the values are constantly too high. What can be the reason?
Factors that influence the concentration of a Karl Fischer titrant
The concentration of the Karl Fischer titrant decreases over the time. What affects the concentration of a Karl Fischer titrant solution?
Poor result repeatability achieved in water determination with volumetric Karl Fischer titration
The result repeatability achieved in water determination according to volumetric Karl Fischer titration is poor. What affects the result repeatability and what measures can be recommended?
Correct sample preparation of solid or semi-solid substances for water determination with volumetric Karl Fischer Titration
The water determination of solid or semi-solid substances shows inconsistent results, sometimes too high, sometimes too low.
