New turbo titrator for moisture analysis

Karl Fischer titrations are used for water content analysis of solvents, powders, pastes, gases, as it provides a quick, reliable and accurate method: this is now applicable to solids and tablets

Karl Fischer titrations are routinely used in a wide spectrum of industries for the water content of solvents, solids, powders, pastes, gases etc as it provides a quick, reliable and accurate method for water content analysis.

For products that do not release water readily, such as chocolate, peanuts, almonds, fudge and pharmaceutical tablets, water content has been traditionally carried out by Loss on Drying (LOD) which can take up to two days for some products to be "completely" dry.

Metrohm now have the answer, using the New Turbo Karl Fischer System.

The sample is physically broken down to a pulp by maceration, chopping and grinding of the sample in situ, in a sealed Karl Fischer vessel.

This seal is important because if this breakdown of the sample is carried out manually samples can gain or lose water depending on the relative humidity during this process: with the sealed vessel this cannot occur.

The maceration time, extraction time and the automatic stop criteria functions of the titration are controlled automatically by the 787 Titrino.
