Simple and Rapid Identification of Vegetable Oils Using a Benchtop MALDI-TOF Mass Spectrometer and eMSTAT SolutionTM Statistical Analysis Software

Introduction

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometers (MALDI-TOF MS) feature simple and rapid detection of low molecular to high molecular weight compounds in a wide range of samples. MALDI-TOF MS is widely used to determine molecular weights of synthesized products and natural substances in R&D laboratories and quality control sectors. In addition, utilizing the feature of MALDI-TOF MS which can detect multiple components in a wide mass range as singly-charged ions (1 component = 1 peak), an attempt is being made to use the instrument for profiling property changes of food and biological specimens. This article introduces an example of simple and rapid identification of vegetable oils, using a benchtop MALDI-TOF MS and the eMSTAT Solution statistical analysis software.
