CALIBRATION

Osmometer calibration procedures

Calibration with osmolality standards

Calibrates the osmometer with certified sodium chloride osmolality standards that bracket the working range, then checks it with a reference solution.

Open procedure
QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines the measuring principle, range, sample volume, repeatability and data integrity requirements.

  2. 02

    IQ — Installation qualification

    Confirms installation, serial number, software version, probe and accessories, and the environment.

  3. 03

    OQ — Operational qualification

    Verifies accuracy and repeatability with certified osmolality standards across the range, and the reference solution check.

  4. 04

    PQ — Performance qualification

    Shows consistent performance through daily reference checks and correct results for a known product or standard.
