Mass Spectrometry Data Processing Apparatus and Mass Spectrometry Data Processing Method |
摘要 |
A mass spectrometry data processing apparatus includes a data analysis unit that processes a mass spectrum of each of analysis-target areas within a two-dimensional range set on a sample. The data analysis unit obtains a plurality of mass spectra each associated with position information of a corresponding one of the analysis-target areas; creates an average mass spectrum that is an average of the plurality of obtained mass spectra; extracts, for each mass range, a highest peak by comparing the plurality of obtained mass spectra with one another, and creates a maximum mass spectrum constituted by the extracted highest peaks; creates an intensity ratio spectrum indicating an intensity ratio of the average mass spectrum to the maximum mass spectrum; and selects a peak in a range of a threshold set for the intensity ratio spectrum and specifies a mass range including the peak. |

1. A mass spectrometry data processing apparatus comprising:
a data analysis unit that processes a mass spectrum of each of analysis-target areas within a two-dimensional range set on a sample, wherein the data analysis unit obtains a plurality of mass spectra each associated with position information of a corresponding one of the analysis-target areas, creates an average mass spectrum that is an average of the plurality of obtained mass spectra, extracts, for each mass range, a highest peak by comparing the plurality of obtained mass spectra with one another, and creates a maximum mass spectrum constituted by the extracted highest peaks, creates an intensity ratio spectrum indicating an intensity ratio of the average mass spectrum to the maximum mass spectrum, and selects a peak in a range of a threshold set for the intensity ratio spectrum and specifies a mass range including the peak. |
