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...
متن کاملChloramphenicol determination in milk by liquid chromatography – tandem mass spectrometry
A high-performance liquid chromatography – tandem mass spectrometry (HPLC– MS–MS) method was developed for the determination of chloramphenicol (CAP) in milk products. Mass spectral acquisition was done using electrospray ionization in the negative ion mode applying multiple reaction monitoring of two diagnostic transition reactions for CAP (m/z 321→152 and m/z 321→257). Milk samples were extra...
متن کاملRapid determination of fosetyl-aluminum residues in lettuce by liquid chromatography/electrospray tandem mass spectrometry.
This paper describes a new method for the sensitive and selective determination of fosetyl-aluminum (Al) residues in vegetable samples. The method involves extraction with water by using a high-speed blender and subsequent injection of the 5-fold diluted extract into the liquid chromatograph. Fosetyl-Al is determined by liquid chromatography with electrospray tandem mass spectrometry after the ...
متن کاملDetermination of Mebudipine in Human Plasma by Liquid Chromatography–tandem Mass Spectrometry
In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...
