Modular Metrohm OMNIS titrator is equipped with Karl Fischer titration unit and 3 dosing modules / burettes for pH or potentiometric titration.

Available methods:

• Volumetric Karl Fischer titration
• pH titration using HCl and pH electrode (optimized for residual alkali determination in black liquor)
• Potentiometric titration using AgNO3 and Ag electrode (for determination of sulfidity HS-)
• pH static program using NaOH and pH electrode

Other titration method can be established upon request.

The titrator is located in a fume hood.
