Liquid chromatographic analysis of vitamin K1 in milk-based infant formula with matrix solid-phase dispersion.
A liquid chromatographic method for vitamin K1 in milk-based infant formula is described. The vitamins are extracted from infant formula by matrix solid-phase dispersion and quantitated by reversed-phase chromatography with fluorescence detection. Vitamin K1 is converted to the fluorescent hydroquinone with a postcolumn zinc reductive reactor. The limit of detection is 12 pg, and the limit of q...
متن کاملChemically Modified Eggshell Membrane as an Adsorbent for Solid-Phase-Extraction of Morphine Followed by High Performance Liquid Chromatography Analysis
In this project, eggshell membrane was used as a solid phase extraction sorbent for extraction of morphine followed by HPLC analysis. At first, raw eggshell membrane was used and then, because of low adsorption of morphine on untreated eggshell membrane (<70%), modification of eggshell membrane surface was carried out using different surfactants and amines. The amine modified eggshells characte...
متن کاملMatrix solid phase dispersion (MSPD).
A review of the many uses of matrix solid phase dispersion (MSPD) in the extraction and analysis of a variety of compounds from a range of samples is provided. Matrix solid phase dispersion (MSPD) has found particular application as a somewhat generic analytical process for the preparation, extraction and fractionation of solid, semi-solid and/or highly viscous biological samples. Its simplicit...
متن کاملUltrasonic-Assisted Matrix Solid-Phase Dispersion and High-Performance Liquid Chromatography as an Improved Methodology for Determination of Oleuropein from Olive Leaves
In this study, ultrasonic-assisted matrix solid-phase dispersion (UA-MSPD) as a new sample preparation method for natural product analysis was developed. Influential parameters of the UA-MSPD method was optimized using oleuropein content of olive leaves as a model analyte. Main parameters of the proposed technique such as ultrasonic time, amplitude and pulse, sorbent material, the ratio of samp...
متن کاملDetermination of pesticide residues in olives and olive oil by matrix solid-phase dispersion followed by gas chromatography/mass spectrometry and liquid chromatography/tandem mass spectrometry.
A novel analytical approach has been developed and evaluated for the quantitative analysis of a selected group of widely used pesticides (dimethoate, simazine, atrazine, diuron, terbuthylazine, methyl-parathion, methyl-pirimiphos, endosulfan I, endosulfan II, endosulfan sulphate, cypermethrin and deltamethrin), which can be found at trace levels in olive oil and olives. The proposed methodology...
