Titration & electrochemistry
Karl Fischer Titrator (Coulometric)
Measures very small amounts of water by generating iodine electrically inside the cell and counting the charge needed to react with all the water. Suited to trace water, from ppm levels up to about 1–5%.

PREVENTIVE MAINTENANCE
Maintenance checklist
Daily / each use
- Check drift before use
- Check reagent capacity counters
- Inspect the septum and replace it if worn
- Check for leaks at joints
Weekly
- Replace anolyte and catholyte as per usage or SOP
- Clean the cell and electrodes
- Check the drying tube molecular sieve
Monthly / quarterly
- Clean the generator electrode and diaphragm (for example with nitric acid, as advised by the supplier)
- Regenerate or replace molecular sieve
- Check the KF oven temperature and gas flow if fitted
Annual
- Preventive maintenance by a trained engineer
- Generator current and charge measurement verification
- Software and audit-trail review
SAFETY
Safety precautions
Before you work on the KF titrator (coulometric)
- KF reagents are toxic and flammable: use in a fume hood or well-ventilated area, away from ignition sources.
- Wear gloves, safety glasses and a lab coat.
- Handle syringe needles carefully and dispose of them in a sharps container.
- Cleaning the generator electrode with acids needs extra care: follow the supplier's instructions.
In LimsPulse · Calibration Management
Keep every KF titrator (coulometric) in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
