Deoxynivalenol and its conjugates in beer: a critical assessment of data obtained by enzyme-linked immunosorbent assay and liquid chromatography coupled to tandem mass spectrometry.

Simultaneous Analysis of Metabolite Residues from Degradation of Dithiocarbamates in Cereals Using Liquid Chromatography Coupled with Tandem Mass Spectrometry

Background and Objectives: Dithiocarbamates are groups of fungicides used to control pests of agricultural products. Analysis of these pesticides with liquid and gas chromatography instruments is associated with various problems due to the presence of metal groups in the structure of these compounds. Therefore, one of the ways for analysis the pesticides is to check the level of decomposition...

Measurement of circulating 25-hydroxy vitamin D using three commercial enzyme linked immunosorbent assay kits with comparison to liquid chromatography - tandem mass spectrometry

Development of a multi-mycotoxin analysis in beer-based drinks by a modified QuEChERS method and ultra-high-performance liquid chromatography coupled with tandem mass spectrometry.

An analytical method was developed for the identification and quantification of 15 mycotoxins (patulin, nivalenol, deoxynivalenol, aflatoxin B(1), B(2), G(1), G(2), M(1), T-2 toxin, HT-2 toxin, zearalenone, fumonisin B(1), B(2), B(3), and ochratoxin A) in beer-based drinks (beer, low-malt beer, new genre, and nonalcoholic) by a modified QuEChERS method and an ultra-high-performance liquid chrom...

Correlation study of enzyme-linked immunosorbent assay and high-performance liquid chromatography/tandem mass spectrometry for the determination of N-methylcarbamate insecticides in baby food

In this work, a correlation study of monoclonal antibody-based enzyme-linked immunosorbent assays (ELISAs) and a liquid chromatography–electrospray mass spectrometric (HPLC/ESI/MS/MS) method for the determination of N-methylcarbamate insecticides carbofuran, carbaryl and methiocarb in fruit baby food is presented. The comparison of performance characteristics of the two methods was carried out ...

Fabrication of a Voltammetric Biosensor in Combination with Enzyme-linked Immunosorbent Assay to Detect Aflatoxin M1 in Milks

Background and Objectives: Aflatoxin M1 is one the most important mycotoxin contaminants of milks. Various methods have been described to detect aflatoxins in milks, including chromatography, enzyme-linked immunosorbent assay and colorimetry. Regarding high sensitivity of electrochemical sensor based methods, the aim of the present study was to fabricate an accurate sensitive voltametric biosen...
