A novel approach based on capillary liquid chromatography for the simultaneous determination of neonicotinoid residues in cereal samples

Posted on 18 December, 2020 by fqm302

A simple and effective method using solid–liquid extraction followed by capillary liquid chromatography with diode array detection (CLC-DAD) has been established for the extraction and determination of seven neonicotinoid insecticides commercially available (imidacloprid, thiacloprid, clothianidin, thiamethoxam, acetamiprid, nitenpyram and dinotefuran) … Continue reading →

Multi-mycotoxin occurrence and exposure assessment approach in foodstuffs from Algeria

Posted on 19 March, 2020 by fqm302

A survey on 120 cereal samples (barley, maize, rice and wheat) from Algerian markets has been carried out to evaluate the presence of 15 mycotoxins (ochratoxin A, deoxynivalenol, fumonisin B1 and B2, T-2 and HT-2 toxins, zearalenone, fusarenon X, citrinin, … Continue reading →

Simple determination of aflatoxins in rice by ultra-high performance liquid chromatography coupled to chemical post-column derivatization and fluorescence detection

Posted on 6 November, 2017 by fqm302

A fast and simple analytical method was developed and characterized for the determination of aflatoxins (B1, B2, G1 and G2) in rice. The procedure is based on a simple solid-liquid extraction without further clean-up, and analysis by ultra-high performance liquid … Continue reading →

Development of magnetic molecularly imprinted polymers for selective extraction: determination of citrinin in rice samples by liquid chromatography with UV diode array detection.

Posted on 23 January, 2017 by fqm302

In this work, we report the synthesis of novel magnetic molecularly imprinted polymers (m-MIPs) and their application to the selective extraction of the mycotoxin citrinin (CIT) from food samples. The polymers were prepared by surface imprinting of Fe3O4 nanoparticles, using … Continue reading →

Simple methodology for the determination of mycotoxins in pseudocereals, spelt and rice

Posted on 4 September, 2013 by fqm302

Nowadays the interest and consumption of pseudocereals is increasing due to their nutritional properties. Like cereals and oilseeds, pseudocereal seeds are susceptible to fungal growth and mycotoxin contamination; however these matrices have received little attention in literature. A sensitive, simple … Continue reading →

On-line preconcentration for the determination of aflatoxins in rice samples by micellar electrokinetic capillary chromatography with laser induced fluorescence detection

Posted on 30 June, 2010 by fqm302

MEKC coupling with LIF detection has been used for the determination of four aflatoxins (B1, B2, G1 and G2). Separations were performed in an uncoated fused-silica capillary (70 cm×75 μm id, 55 cm effective length), using 20 mM borate buffer with 30 mM SDS (pH … Continue reading →
