Rapid Analysis and Structural Analysis of the Components in Foods Using DART and the LCMS-9030

User Benefits

- The system can perform analysis without pretreatment, regardless of whether the sample is solid, liquid, or gas. - Using this workflow, a structural analysis of the components in foods can be performed with high mass accuracy. - Compositional formula estimates, compound searches, and fragment attribution analysis can be performed using the LabSolutions Insight Explore^TM analysis software.

Introduction

In developing food and beverage products, obtaining information on the constituent components is important for maintaining and improving quality. Normally, however, when measuring specific components in foods and beverages, extraction and other troublesome pretreatments are often necessary. Direct Analysis in Real Time (DART^®) is a method for the direct ionization of samples. It is effective for simple screening because it enables measurements to be performed quickly without pretreatment regardless of whether the sample is solid, liquid, or gas. In this article, the combination of DART and the LCMS-9030 quadrupole time-of-flight mass spectrometer (Q-TOF) is used to measure the components in foods, using chili oil as an example. Structural analysis of the components in the sample is performed with high mass accuracy, using the LabSolutions Insight Explore analysis software based on the MS/MS spectral information obtained. The IonSense DART-OS was used as the ion source.
