Vacuum Oven

A sealed, heated chamber connected to a vacuum pump. Lowering the pressure lets samples dry at a lower temperature, which suits heat-sensitive materials and LOD tests done 'in vacuum'.

CALIBRATION

Vacuum oven calibration procedures

Temperature accuracy

Compares the oven display with a calibrated temperature probe on the shelf at the drying temperatures used.

Open procedure

Vacuum gauge check

Compares the oven's vacuum gauge with a calibrated reference vacuum gauge at several pressures.

QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines temperature range, vacuum level, chamber size, pump type and solvent compatibility.

  2. 02

    IQ — Installation qualification

    Confirms correct installation of oven, pump, trap and exhaust, with documentation.

  3. 03

    OQ — Operational qualification

    Checks temperature accuracy and uniformity, vacuum reached and held, and gauge accuracy.

  4. 04

    PQ — Performance qualification

    Shows consistent drying performance under the conditions used for routine tests.
