Products description Products characteristic technical specification

The AQUA 40.00 Vario Headspace 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

  • Patented closed-loop gas circulation technology, no external carrier gas required
  • Really measure moisture with PPM level accuracy
  • Save a lot of testing time
  • Extend the life of Karl Fischer reagents
  • Temperature control program can distinguish free water and bound water
  • Multiple types of automatic sampling tray adaptation
  • Resolution: 0.1ug
  • Repeatability: 10~1000ug±3μg
