Chemically 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 کاملDetermination of urinary pyrraline by solid-phase extraction and high performance liquid chromatography.
Pyrraline is one of the advanced glycation end products formed under non-enzymatic and non-oxidative conditions in vivo. In this study, we developed a novel method for determination of urinary pyrraline using solid-phase extraction as a pretreatment procedure prior to determination by high performance liquid chromatography (HPLC). The Oasis HLB solid-phase extraction cartridge was used for pret...
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 کاملPreconcentration and Determination of Mefenamic Acid in Pharmaceutical and Biological Fluid Samples by Polymer-grafted Silica Gel Solid-phase Extraction Following High Performance Liquid Chromatography
Abstract Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic,anti-infammatory and antipyretic actions. It is used to relieve mild to moderate pains. Solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . Poly allyl glycidyl ether/iminodiacetic acid-co-N, N-dimethylacrylamide was synthesized and grafted to silica gel and was used ...
