Cai J, Xin H, Cheng L, Fu Y, Jiang D, Feng J, Fu Q, Jin Y, Liang X.
PMID: 28865331
J Chromatogr B Analyt Technol Biomed Life Sci. 2017 Sep 15;1063:149-155. doi: 10.1016/j.jchromb.2017.08.034. Epub 2017 Aug 31.

The goal of this study was to develop a method that utilized a hydrophilic C18 stationary phase in the preparative high performance liquid chromatography to isolate the polar part from the rhizomes of Anemarrhena asphodeloides. The results showed that...

Optimization and evaluation of radially interconnected versus bifurcating flow distributors using computational fluid dynamics modelling.

Journal of chromatography. A

Davydova E, Deridder S, Eeltink S, Desmet G, Schoenmakers PJ.
PMID: 25591402
J Chromatogr A. 2015 Feb 06;1380:88-95. doi: 10.1016/j.chroma.2014.12.063. Epub 2014 Dec 30.

Two main groups of flow distributors, viz. "bifurcating distributors" (BF) and "radially interconnected distributors" (RI), as well as some hybrid distributors were investigated. Computational fluid dynamics was used to evaluate the performance of the distributors and to establish the...

An environmentally friendly method for the determination of pentachlorophenol in paper packaging materials using ultrasonic-assisted micellar extraction.

Journal of chromatographic science

Yang F, Li Z, Bian Z, Wang Y, Fan Z, Liu S, Zhang H, Tang G.
PMID: 26136274
J Chromatogr Sci. 2015 Nov-Dec;53(10):1808-12. doi: 10.1093/chromsci/bmv076. Epub 2015 Jun 30.

Ultrasonic-assisted micellar extraction coupled with high-pressure liquid chromatography has been developed for the determination of pentachlorophenol (PCP) in paper packaging materials. A non-ionic surfactant, polyethylene glycol sorbitan monolaurate (Tween 20), was used for ultrasonic extraction and the method was...

Improvement in Liquid Chromatographic Performance of Organic Polymer Monolithic Capillary Columns with Controlled Free-Radical Polymerization.

Journal of chromatographic science

Gama MR, Aggarwal P, Liu K, Lee ML, Bottoli CB.
PMID: 27993839
J Chromatogr Sci. 2017 Apr 01;55(4):398-404. doi: 10.1093/chromsci/bmw193.

Capillary columns containing butyl or lauryl methacrylate monoliths were prepared using two different free-radical polymerization methods: conventional free-radical polymerization and controlled/living free-radical polymerization, both initiated thermally, and these methods were compared for the first time. Both monolith morphology and...
