Application of MS Imaging to Food Science and Safety Using the MALDI-8020 Benchtop MALDI-TOF Mass Spectrometer

User Benefits

- Rapid and easy MS imaging analysis using a benchtop MALDI-TOF MS - Distribution of a pesticide in plant seeds and oligomers on film surfaces can be observed at a spatial resolution of 50 μm. - MS imaging enables evaluation of the surfaces of various food-related and industrial materials.

Introduction

MS imaging is one of the fastest-growing mass spectrometry applications in recent years. In this technique, a target substance is measured directly from a surface without any labeling or derivatization. Therefore, this technique is often used to visualize the distribution of substances, for example, drug metabolites in biological organisms or functional ingredients in food, which are often difficult label/derivatize. In this report, we introduce two examples of MS imaging at a spatial resolution of 50 μm: a pesticide on the surface of a plant seed and heat-induced deterioration of food contact material.
