Patent ID: 8766172

Claim:
A method for analyzing a sample, comprising: performing processing to analyze the sample, said processing including performing chromatographic separation, ion mobility spectrometry and mass spectrometry with respect to said sample; obtaining, in accordance with said processing to analyze said sample, noisy raw data comprising a set of data elements each associating an ion-count intensity with at least three dimensions, wherein the noise is associated with ion-peak artifacts, wherein the at least three dimensions include a retention time dimension, an ion-mobility dimension, and a mass-to-charge ratio dimension; convolving at least some of the noisy raw data with an artifact-reducing filter associated with a matrix having the same number of dimensions as the noisy raw data thereby obtaining a convolved set of the at least some of the noisy raw data; and locating one or more ion peaks in the convolved set of the at least some of the noisy raw data.
