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%.

CALIBRATION

KF titrator (coulometric) calibration procedures

Water standard recovery

Injects a certified liquid water standard and checks that the coulometer finds the certified amount of water.

Open procedure

Drift check

Records the background drift of the conditioned coulometric cell and checks it is low and stable before analysis.

Open procedure
QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Documents the requirements: water range, cell type (with or without diaphragm), oven option, drift measurement and software with audit trail.

  2. 02

    IQ — Installation qualification

    Confirms delivery and installation: control unit, cell, electrodes, oven, serial numbers, software version and manuals.

  3. 03

    OQ — Operational qualification

    Verifies drift performance, generator current accuracy and recovery of certified water standards at more than one level.

  4. 04

    PQ — Performance qualification

    Shows routine performance over time with regular water-standard recoveries and drift records within limits.

In LimsPulse · Calibration Management

Keep every KF titrator (coulometric) in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
