Qualitative Analysis of the Components in Foods Using DART and the Quadrupole Time-of-flight Mass Spectrometer

User Benefits

- The system can perform analysis without pretreatment, regardless of whether the sample is solid, liquid, or gas. - Qualitative analysis can be performed with high mass accuracy, using positive/negative ion polarity switching without mass calibration by internal standard. - Formula estimates, compound searches, and fragment attribution analysis can be performed by this workflow.

Introduction

In developing food and beverage products, obtaining information on the constituent components is important for maintaining and improving quality. Among them, the aroma constituents are attracting attention as an index of flavor. 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-OS (IonSense, Inc.) and the LCMS-9050 quadrupole time-of-flight mass spectrometer (Q-TOF) was used to measure the components in chocolate Structural analysis of the components in the sample was performed with high mass accuracy, using the LabSolutions Insight Explore analysis software based on the MS/MS spectral information obtained.
