Determination of DiazaCon in quail feed and quail serum by ion pair reversed-phase chromatography.
Liquid chromatographic (LC) methods were developed for quantitating the potential avian contraceptive DiazaCon in quail feed and serum. DiazaCon was extracted from ground quail feed with basic n-butyl chloride. The n-butyl chloride extract was evaporated to dryness. The DiazaCon residues were dissolved in an aqueous methanolic ion pairing solution and quantitated by LC at 206 nm. Avian sera was...
متن کاملFurosine Determination in Baby Cereals by Ion-Pair Reversed-Phase Liquid Chromatography
Cereal Chem. 73(6):729-731 A simple procedure for the determination of &-N-2-furoylmethyl-Llimit was 1.42 pmol. Furosine formation by sample hydrolysis with hylysine (furosine) in baby cereals is reported. Furosine was quantified in drochloric acid increased with acid concentration to 10.6M. The content acid hydrolysates by isocratic ion-pair reversed-phase liquid chromatogof furosine found in ...
متن کاملDetermination of urinary oxalate by reversed-phase ion-pair "high-performance" liquid chromatography.
In this liquid-chromatographic method for determination of urinary oxalate, interfering compounds in the urinary samples were eliminated before chromatography by passage through a preparative C18 mini-column (Sep-pak cartridge, Waters Associates). In the reversed-phase system tetrabutyl ammonium was included as a counter ion to enhance the retention of oxalate. The pH of the mobile phase was ke...
متن کاملThiocyanate determination by ion pair chromatography
Department of Analytical and Environmental Chemistry, Vilnius University, Naugarduko 24, LT-03225 Vilnius, Lithuania A simple and rapid ion pair chromatographic method has been developed for the determination of thiocyanate. Separation was carried out on a 25 cm × 4.6 mm Ascentis C18 column (5 μm particle size) with a mobile phase containing 2 mmol/l tetrabutylammonium (TBA)-phosphate (pH 6.5) ...
متن کاملDetermination of Fluorescent Whitening Agents in Paper Materials by Ion-Pair Reversed-Phase High-Performance Liquid Chromatography
A simple method was developed for the analysis of seven stilbene-type fluorescent whitening agents (FWAs) in paper materials by ion-pair reversed-phase high-performance liquid chromatography with fluorescence detection. These stilbene-type FWAs included two disulfonate, two tetrasulfonate, and three hexasulfonate compounds. After optimization of chromatographic conditions, the FWAs were satisfa...
