Contaminant Analysis by DPiMS-2020 (2):Detection of Agricultural Chemicals in Beverages

User Benefits

- The PESI method enables quick and simple analysis without complex sample preparation. - A simple technique for judgment of the presence of agricultural chemicals in beverages was developed. - Simple and high sensitivity screening for the presence of contamination by foreign substances is possible.

Introduction

In incidents involving contamination or adulteration of beverages and foods, a diverse range of cases has been reported, including contamination by familiar chemical substances. For this reason, it is necessary to treat an extremely large number of chemical substances as analysis targets in inspections of beverages and foods in which contamination is suspected. To conduct this kind of analysis efficiently, it is necessary to develop a quick and accurate screening technique for the presence of contaminants. In this article, a high sensitivity detection technique which requires only minimal sample preparation was developed using the DPiMS-2020 direct probe ionization mass spectrometer, assuming contamination of beverages by agriculture chemicals as an example of contamination. The results of a study of the possibility of applying this technique as a simple contamination screening method for beverages suspected of contamination are also reported.
