Raman spectrometric data cleansing

Thermo Fisher Scientific has been awarded a US Patent on Spectrometric Data Cleansing. This patent describes a method for filtering artefacts from Raman spectra and is of particular use in removing the distorted data points generated by cosmic ray interference. Elimination of spectral artefacts facilitates automated analysis by such methods as reference library searches and correlation with standard spectra.

The patented method, unlike more primitive correction schemes, introduces rigorous and objective criteria to the identification and removal of spurious data points. This ensures that spectrometric data cleansing is independent of the skill and judgment of the user and is therefore of immense value to laboratories where expert and non-expert users alike depend on Raman spectroscopy as a prime analytical tool. It is particularly important for those laboratories operating in regulated environments with a need to validate analytical methods.

Raman is routinely used for compound identification, defect analysis and in QA/QC environments. It is an invaluable tool in various industries including chemicals, petroleum, polymers, nanotechnology, alternative energy sources, pharmaceuticals and forensics.
