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.

PREVENTIVE MAINTENANCE

Maintenance checklist

Daily / each use

  • Wavenumber verification check
  • Clean the probe window and nose cone
  • Inspect fibre-optic cables (bench systems)

Monthly

  • Trend verification results and laser power
  • Check battery health on handheld units
  • Review library for pending updates

Annual

  • Calibration of wavenumber accuracy with an external certified standard
  • Laser power and intensity (relative response) check
  • Preventive maintenance by a trained engineer
SAFETY

Safety precautions

Before you work on the Raman
  • Raman lasers are commonly Class 3B: never look into the beam or point it at people.
  • Wear laser safety glasses rated for the laser wavelength when the beam path is open.
  • Do not remove interlocked covers or defeat interlocks.
  • Dark powders can heat or ignite under the laser; test with low power first.
  • Follow the material's safety data sheet when handling raw materials.
In LimsPulse · Calibration Management

Keep every Raman in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
