Thermo Fisher Scientific Inc. announces that it has been awarded a US Patent on Spectrometric Data Cleansing. This patent describes a method for filtering artifacts from Raman spectra and is of particular use in removing the distorted data points generated by cosmic ray interference. Elimination of spectral artifacts 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 judgement 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, alternate energy sources pharmaceuticals and forensics.
This method for Spectrometric Data Cleansing, patented under US Patent Number 7,233,870 B1, is incorporated into the Thermo Scientific OMNIC software suite and is standard with the Nicolet Almega XR dispersive Raman microscope.
