Quantitative determination of trichothecenes in breadsticks by gas chromatography-triple quadrupole tandem mass spectrometry.
Breadsticks are pencil-sized sticks of dry bread widely consumed as a pre-meal appetiser. They are basically wheat-based snacks, which makes them a good matrix to evaluate mycotoxin contamination, since wheat is very susceptible to fungal attack. In this sense, the fast, selective and sensitive gas chromatography-triple quadrupole tandem mass spectrometry (GC-QqQ-MS/MS) method proposed here all...
متن کاملMatrix interference evaluation employing GC and LC coupled to triple quadrupole tandem mass spectrometry.
Gas and liquid chromatography coupled to triple quadrupole tandem mass spectrometry are currently the most powerful tools employed for the routine analysis of pesticide residues in food control laboratories. However, whatever the multiresidue extraction method, there will be a residual matrix effect making it difficult to identify/quantify some specific compounds in certain cases. Two main effe...

15 صفحه اولDetermination of PFOS and PFOA in Food Matrix of Animal Origin Using UHPLC Hyphenated Triple Quadrupole Tandem Mass Spectrometry* Authors
An ultrasensitive method has been developed for simultaneous determination of perfluorooctane sulfonates (PFOS) and perfluorooctanoic acid (PFOA) in food using an Agilent UHPLC 1290 hyphenated Triple Quadrupole 6460 tandem mass spectrometer. The samples were first extracted using methanol, followed by cleanup with weak anion-exchange cartridge. The resultant solutions were subjected to reversep...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
