Simultaneous Determination of Four Preservatives in Foodstuffs by High Performance Liquid Chromatography
Background and objectives: High concentration of preservatives in food may result in gastrointestinal disturbances whereby some patients suffering from asthma, rhinitis, or urticaria. The aim of this study is the introduction and optimization a new method for simultaneous determination of four preservatives (SB, PS, MP, PP) in foodstuff by high performance liquid chromatography. Materi...
متن کاملSimultaneous determination of five fat-soluble vitamins in feed by high-performance liquid chromatography following solid-phase extraction.
A high-performance liquid chromatography method is developed for the simultaneous determination of menadione, retinyl acetate, cholecalciferol, alpha-tocopherol, and alpha-tocopherol acetate in feed. The present study uses an enzyme to destroy the coating film, ethanol to extract free vitamins, and Oasis HLB cartridges to purify. Vitamins are separated using an Atlantis dC18 column. The mobile ...
متن کاملSimultaneous determination of bisphenols and alkylphenols in water by solid phase extraction and ultra performance liquid chromatography-tandem mass spectrometry.
To establish an analytical method for determination of four bisphenols (BPA, BPB, BPF, and BPS) and two alkylphenols (4-n-OP, 4-n-NP) in water by ultra performance liquid chromatography- tandem mass spectrometry (UPLC/MS/MS). The water samples were extracted and condensed with solid-phase extraction (SPE) using C18 cartridges and eluted by acetonitrile. Separation was carried out with Acquity B...
متن کاملSimultaneous determination of phenolic xenoestrogens by solid-phase extraction and high-performance liquid chromatography with fluorescence detection.
A highly sensitive and selective method for simultaneous determination of some hydroxyl group-containing endocrine disruptors, including bisphenol A (BPA), bisphenol B (BPB), bisphenol E (BPE), bisphenol F (BPF) and 4-nonylphenol (4-NP), was developed. The method consists of precolumn derivatization of the analytes, solid-phase extraction (SPE) and subsequent chromatographic analysis by high-pe...
