Raman spectrometer

Shines a laser on a sample and measures the tiny fraction of light scattered with a shifted wavelength. Gives a sharp molecular fingerprint through glass and plastic, ideal for raw-material identity and polymorph checks.

CALIBRATION

Raman calibration procedures

Wavenumber accuracy

Checks the Raman shift (x-axis) scale by measuring a standard with well-known band positions, such as cyclohexane, polystyrene or paracetamol (4-acetamidophenol), and comparing the observed bands with the reference values.

QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines laser wavelength, spectral range, resolution, sampling accessories, library software and data integrity requirements.

  2. 02

    IQ — Installation qualification

    Confirms components, laser class labels, interlocks, software version and documentation.

  3. 03

    OQ — Operational qualification

    Checks wavenumber (x-axis) accuracy, laser wavelength, spectral resolution, intensity response and laser power with certified standards.

  4. 04

    PQ — Performance qualification

    Demonstrates correct identification of target materials and rejection of challenge materials with the validated library, plus routine daily checks.
