Statistical Interpretation of Crude Oil High Resolution Spectra obtained by APPI Fourier Transform Ion Cyclotron Resonance Mass Spectrometry using Principal Component Analysis

摘要

The high resolution capability of Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has had high impact on crude oil analysis since FT-ICR MS spectra provide a wealth of chemical information. However, the sheer amount of information can cause a problem when it is necessary to examine or compare mass spectra in detail. Therefore, statistical analysis is a reasonable approach to deal with a large amount of data. In this study, a statistical program was developed for the PCA analysis of high resolution mass spectra and it was successfully applied to crude oil's spectra.
