CALIBRATION

Fibre analyser calibration procedures

Recovery check with a reference material

Runs a reference material with a known crude fibre value through the full procedure and compares the result with the assigned value.

Open procedure
QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines the number of positions, reagent heating, vacuum system, crucible type and compatibility with the crude fibre standard used.

  2. 02

    IQ — Installation qualification

    Records the unit, cooling water, vacuum, drain and power connections, plus crucible identification.

  3. 03

    OQ — Operational qualification

    Checks reagent heating, boiling time control, vacuum filtration and pressure functions.

  4. 04

    PQ — Performance qualification

    Shows results on a reference material agree with its assigned value and duplicates meet method repeatability.
