Simultaneous extraction and determination of trace amounts of diclofenac from whole blood using supported liquid membrane microextraction and fast fourier transform voltammetry

19-Jan-2018 | Zahra Mofidi, Parviz Norouzi, Masumeh sajadian, Mohammad Reza Ganjali, Journal of Separation Science, 2018

Abstract A novel, simple and inexpensive analytical technique based on flat sheet supported liquid membrane microextraction coupled with fast Fourier transform stripping cyclic voltammetry on a reduced graphene oxide carbon paste electrode was used for the extraction and online determination ...

Enantiomeric separation of six chiral pesticides that contain chiral sulfur/phosphorus atoms by supercritical fluid chromatography

16-Jan-2018 | Lijun Zhan, Yelong Miao, Chunmian Lin, Journal of Separation Science, 2018

Abstract Six chiral pesticides containing chiral sulfur/phosphorus atoms were separated by supercritical fluid chromatography with supercritical CO2 as the main mobile phase component. The effect of the chiral stationary phase, different type and concentration of modifiers, column temperature, ...

Preparation and evaluation of a deoxycholic‐calix[4]arene hybrid‐type receptor as a chiral stationary phase for HPLC

15-Jan-2018 | Sadegh Yaghoubnejad, Kourosh Tabar Heydar, Seyyed Hamid Ahmadi, Reza Zadmard, Nima Ghonouei, Journal of Separation Science, 2018

Abstract We report the synthesis and enantioseparation characteristics of two novel covalently immobilized deoxycholic acid derivatives as chiral stationary phases for high-performance liquid chromatography. In the structure of the first stationary phase, the 3-position of deoxycholic acid is ...

Selective enrichment of N‐linked glycopeptides and glycans by using a dextran‐modified hydrophilic material

15-Jan-2018 | Linlin Chen, Di Ding, Qianying Sheng, Long Yu, Xiuping Liu, Xinmiao Liang, Journal of Separation Science, 2018

Abstract Glycosylation analysis of proteins from biological sources utilizing mass-spectrometry-based approaches is challenging due to the relatively low abundance of glycopeptides, the structural diversity of glycans as well as the co-existing matrices. In this study, a customized ...

Selective extraction of bisphenol a from water by one‐monomer molecularly imprinted magnetic nanoparticles

15-Jan-2018 | Zhenkun Lin, Yanfang Zhang, Yu Su, Jinxia Qi, Yinhang Jia, Changjiang Huang, Qiaoxiang Dong, Journal of Separation Science, 2018

Abstract One-monomer molecularly imprinted magnetic nanoparticles were prepared as adsorbents for selective extraction of bisphenol A from water in this study. A single bi-functional monomer was adopted for preparation of the molecularly imprinted polymer, avoiding the tedious trial-and-error ...

High‐capacity protein A affinity chromatography for the fast quantification of antibodies: Two‐wavelength detection expands linear range

13-Jan-2018 | Peter Satzer, Alois Jungbauer, Journal of Separation Science, 2018

Abstract The high-throughput analysis of antibodies from processes can be enhanced when the linear range is expanded and sample preparation is kept to a minimum. We developed a fast chromatography method based on a hexameric variant of Staphylococcal protein A immobilized on Toyopearl matrix, ...
