Karl Fischer titrator AQUA 40.00 Vario
Water determination in all types of samples
Product description
TOP 3 ADVANTAGES
- Closed-loop circulation of extraction gas
- Manual and automatic version available
- Easy to adapt to different vial sizes
Water determination by headspace technique
The AQUA 40.00 Vario combines the Karl Fischer Titration with the headspace technique. This offers a wide range of interesting applications to determine moisture in solid and pasty samples, oils and viscous compounds.
The sample preparation takes place using the dynamic headspace technique. The sample - in a closed vial - is placed into the headspace oven and tempered.
A closed-loop gas circulation with dry carrier gas flows across the sample and transports the extracted water completely into the measuring cell, where the analysis is carried out by titration according to the Karl Fischer method.
It does not require time-consuming sample preparation:
Weigh out the sample into the headspace vial and close it
Place the vial in the device (manually or automatically)
Prepare the measurement and start it
