Sample preparation
OMNIS, the modular platform for chemical analysis from Metrohm has become ever more powerful. With the launch of the OMNIS Coulometer, users of OMNIS now have the complete scope of titration methods at their disposal.
Coulometry is the preferred method for trace-level determination of moisture in liquid, solid, and gaseous matrices. It is simple to use, results are available in less than three minutes, and as coulometry is an absolute method, a titre determination is not required.
The OMNIS Coulometer offers maximum flexibility: if the sample volume increases, users can add another OMNIS Coulometer module. Adding an OMNIS Dosing Module to the OMNIS Coulometer eliminates the risk of exposure to the KF reagent enabling the fully automated exchange of exhausted reagent.
Together with the OMNIS Coulometer, Metrohm launches the OMNIS Sample Robot Oven for gas extraction. Gas extraction enables moisture determination in matrices that cannot be analysed directly in the titration cell. The OMNIS Sample Robot Oven can be fitted with one or two Oven Modules for maximum flexibility and increased performance. A maximum of 100 samples in standard vials with a volume of 6 mL can be analysed for moisture content completely unattended.
