Coulometer: Karl Fischer Coulometric Titrator - 10 µg to 200 mg Water - Diaphragm-Free Electrode

Metrohm 917 Coulometer for Trace Water Determination

Volumetric Karl Fischer titration struggles at trace water levels and needs regular titer checks. The Swiss Metrohm 917 Coulometer is a compact coulometric KF titrator; coulometry is an absolute method, so no titer determination is needed.

With operating module, stirrer and pump integrated, the Metrohm 917 Coulometer (2.917.0110, generator electrode without diaphragm) saves bench space and allows rapid reagent replacement.

Key Benefits

Efficiency

Integrated pump and stirrer make reagent changes quick on the Metrohm 917 Coulometer. See the Metrohm 917 Coulometer page.

Accuracy

As an absolute method, coulometry needs no titer and suits trace water down to 10 µg. Weigh samples on our analytical balance.

Safety and comfort

The built-in pump handles reagent exchange, and audit trail support in the Metrohm 917 Coulometer meets 21 CFR Part 11.

Key Features

• Coulometric KF, no titer determination
• 10 µg - 200 mg water range
• Integrated stirrer and pump
• Diaphragm-free generator electrode
• 21 CFR Part 11 compliant

Solving Common Lab Problems

Trace water too low for volumetric KF? The Metrohm 917 Coulometer works from 10 µg.

Titer drifts? Coulometry is absolute, no titer needed.

Audit requirements? The Metrohm 917 Coulometer software fulfils FDA 21 CFR Part 11.
