Thermo Fisher Scientific is awarded US spectrometric data cleansing patent

Thermo Fisher Scientific Molecular Spectroscopy : 09 January, 2008  (New Product)
Thermo Fisher Scientific has been awarded a US patent on spectrometric data cleansing that 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 enables 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. Raman spectroscopy is a useful tool in various industries including nanotechnology, pharmaceuticals and forensics. .

The 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 Ramanmicroscope.
