Automated accuracy and precision

Automation of the Karl Fischer analysis yields two powerful benefits:

• First, the 774 Oven Sample Processor requires minimal preparation, so you are free to perform other tasks in the lab
• Perhaps more important is the increase in accuracy and precision as well as the reduction of bias in the results

With the 774 KF Oven Sample Processor, the same procedure is followed every time, regardless of the technique of the operator, which ensures consistency and reproducibility.

The 774 KF Oven Sample Processor combines the proven reliability of Metrohm Sample Processors with the application range of a Karl Fischer oven. Samples are kept in vials on the sample rack. The vials are then placed, one at a time, into a heating chamber and purged with dried air or nitrogen gas. This gas stream quantitatively transports all the moisture into the titration cell. Moisture content is then determined automatically either coulometrically or volumetrically.
