OMNIS KARL FISCHER TITRATOR

Significance of the Topic

The accurate determination of water content is critical across pharmaceuticals, chemicals, food, and environmental analysis. Karl Fischer titration remains a gold standard due to its specificity and sensitivity. Innovations that enhance safety, automation, and throughput address common challenges of reagent handling, manual intervention, and sample exposure to ambient moisture.

Objectives and Study Overview

This application note introduces the OMNIS Karl Fischer titration system. The aim is to demonstrate how modular hardware and software licensing enable safer, more reliable, and higher-throughput volumetric water determinations across diverse sample matrices.

Methodology and Instrumentation

The OMNIS platform integrates:

• A closed-cell Karl Fischer titration module to prevent direct user contact with solvents and reagents.
• Automatic titration start functionality triggered upon sample injection, eliminating timing errors and sample loss.
• Optional OMNIS Dis-Cover sample changer robot for sealed handling of up to 50 samples, preventing ambient moisture ingress.
• Modular firmware packages (Basic, Advanced, Professional) activating potentiometric measurement, dosing, calibration, conductivity, and titration features as required.
• An OMNIS Solvent Module for contact-free reagent exchange, either manual or automated.

Key Results and Discussion

Implementing the OMNIS Karl Fischer titrator offers:

• Enhanced user safety by fully enclosing reagent and solvent handling steps.
• Improved reliability through automated titration initiation, reducing repeat analyses.
• High throughput via unattended processing of up to 50 samples, with airtight protection against moisture uptake.
• Scalable functionality via license-based firmware enabling custom configurations.
