The 885 compact oven sample changer from Metrohm is said to be an ideal instrument for automated thermal sample preparation in Karl Fischer titration.
The instrument features a small footprint and is flexible and easy to use.
It can be used with all standalone Karl Fischer titrators with sample table and for volumetric and coulometric titrations.
The 885 compact oven sample changer is said to be ideally suited for automating the preparation of samples that release water only at high temperatures, are difficult to dissolve, or react with the Karl Fischer reagent.
In the oven, the samples can be heated to a temperature of 250C.
The moisture contained in the samples evaporates and is transported by a stream of dry carrier gas into the titration cell, where the analysis takes place.
The 885 compact oven sample changer is controlled by an integral keypad.
Only the oven temperature and the gas flow need to be defined and the number of samples set.
If the titrator is linked to a balance, the weight of the samples does not need to be entered manually.
Screw-cap vials are used with the 885 compact oven sample changer.
They can be opened and cleaned after the analysis, and can then be re-used.
Only the pierced septa need to be replaced.
