Determination method of clomeprop and clomeprop acid in livestock and seafood products by LC-MS/MS.
A method using liquid chromatography with tandem mass spectrometry has been developed for the determination of clomeprop and its metabolite clomeprop acid in livestock and seafood products. Clomeprop and clomeprop acid were extracted with acetone-n-hexane mixture under acidic conditions, and were defatted by liquid-liquid separation using acetonitrile and n-hexane, followed cleanup with SAX and...
متن کاملDetermination of Penicillins Residues in Livestock and Marine Products by LC/MS/MS
Multi-residue analysis method for penicillins was developed and validated in bovine muscle, chicken, milk, and flatfish. Detection was based on liquid chromatography tandem mass spectrometry (LC/MS/MS). The developed method was validated for specificity, precision, recovery, and linearity. The analytes were extracted with 80% acetonitrile and clean-up by a single reversed-phase solid-phase extr...
متن کامل[Determination of pindone in agricultural products by LC-MS/MS].
A sensitive and selective analytical method for the determination of pindone in agricultural products by LC-MS/MS was developed. Pindone was extracted with acetone, and an aliquot of the crude extract was re-extracted with hexane. For lipid-rich samples, the crude extract was further cleaned up by acetonitrile-hexane partitioning. The extract was cleaned up on a tandem graphitized carbon-silica...
متن کاملdetermination of olanzapine and thiourea using electrodes modified by dna and film of copper-cobalt hexacyanoferrate & investigation of electro-oxidation of some catechol derivatives in the presence of 4-phenylsemicarbazid
چکیده هدف از این کار بررسی الکترواکسیداسیون کتکول و مشتقات آن در حضور 4-فنیل سمی کاربامازید بوده است اکسیداسیون کتکولها ترکیبات نا پایدار کینونها را تولید می کنند که این ترکیبات می تواند در واکنش مایکل بعنوان پذیرنده نوکلئوفیل عمل نمایند. در ادامه اکسایش کتکولهای (a-c1) را درحضور 4-فنیل سمی کاربامازید در محلول آب/استونیتریل (90/10)بوسیله ولتامتری چرخه ای و کولن متری در پتانسیل ثابت مورد بررسی ...
15 صفحه اولDetermination of pKa Values of Some Sulfonamides by LC and LC-PDA Methods in Acetonitrile-Water Binary Mixtures
As constantes de dissociação de sete sulfonamidas antibióticas, sulfadiazina, sulfatiazol, sulfamerazina, sulfametazina, sulfamonometoxina, sulfadoxina e sulfametoxazol, foram determinadas em diferentes misturas binárias acetonitrila-água (15, 30, 40, 50% (v/v)) usando cromatografia líquida de fase reversa. Um método usando espectros de absorbância no máximo dos picos cromatográficos previament...
