Multivariate analysis and other data minding technique to visualize LC/MS data

Abstract

Liquid chromatography/quadrupole time-of flight-mass spectrometry (LC/TOFMS), which combined a new data minding technique and multivariate analysis, enabled the visualization of LC/MS data. Target screening and non-target screening methods for the multi residue analysis of pesticides in food stuff by LC/TOFMS using a new data minding technique, such as Molecular Feature Extraction (MFE) were described. Furthermore, multivariate analysis and a data minding technique, such as MFE for the identification of the unique compound in food stuff and an adequate classification of crops were useful techniques. © 2014 The Japan Society for Analytical Chemistry.
