Karl Fischer titration
Automated coulometric KF titrations
MATi 4 is a fully automated system for coulometric
KF titrations with high sample throughput. The sample
rack of the 815 Robotic USB Sample Processor XL
accommodates up to 160 samples in 6 mL vials. The
786 Swing Head, transfer version, together with an
800 Dosino transfers the samples to an external coulometric
cell where the KF titration takes place. The
system is controlled by the tiamo titration software.

MATi 10 Automated volumetric KF titrations
The samples are weighed out into beakers, sealed to
protect them against atmospheric moisture and placed
on the rack. Prior to titration the samples are dissolved
in a known amount of KF working medium and the
water content is then titrated in a second step.
This method is particularly suitable for samples that dissolve
quickly in the KF working medium. The solubility
can also be improved by the use of a suitable solubility
promoter.
