Determination of Multiple Mycotoxins in Grain Using a QuEChERS Sample Preparation Approach and LC-MS/MS Detection
Introduction Mycotoxins are toxic secondary metabolites that are naturally produced by several species of fungi on agricultural products, particularly grain-based products. Mycotoxins are chemically stable and cannot be destroyed during food processing and heat treatment. Therefore, they may occur in the field, in raw materials during storage, and in processed foods. To date, more than 300 myco...
متن کاملDetermination of 24 Pesticide Residues in Red Wine Using a QuEChERS Sample Preparation Approach and LC-MS/MS Detection
This application presents a fast, easy, and cost-effective method for the determination of 24 pesticide residues in red wine. Sample preparation involves the extraction of pesticides from red wine using the QuEChERS extraction method (AOAC version). The samples then undergo cleanup by dispersive solid-phase extraction (dSPE) using primary secondary amine (PSA) sorbent, which effectively retains...
متن کاملQuEChERS Sample Preparation for LC/MS and LC/UV Determination of Carbendazim and Other Conazole Fungicides in Orange Juice
IN T RODUC T ION QuEChERS methodology is commonly used for sample preparation of fruits and fruit juices, prior to LC/MS or other analytical chromatography. Recently, a nonregistered fungicide residue, carbendazim, was detected in orange juice purchased at a local market. This juice was produced from orange juice concentrate imported into the USA. In this application note, we discuss sample pre...
متن کاملAutomated Sample Preparation and Analysis Workflows for Pesticide Residue Screening in Food Samples using DPX- QuEChERS with LC-MS/MS
QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation methods have been developed to help monitor pesticides in a range of food samples. These methods require many manual steps, such as shaking, centrifugation, and dispersive SPE cleanup, making it a quite labor-intensive process. There is a need for automating parts of QuEChERS extraction in order to improve laboratory ...
متن کاملDetermination of Halosulfuron-Methyl in Bell Peppers Using QuEChERS and CE/MS/MS
This application note describes a fast analytical method for determination of halosulfuron-methyl using QuEChERS and capillary electrophoresis tandem mass spectrometry (CE/MS/MS). The method was developed and validated for halosulfuron-methyl in green and yellow bell peppers. It showed good linearity (R2 > 0.999) from 5.0 to 500 ppb for the analytical curves prepared in background electrolyte a...
