Autor: Xinyue Ma, Xiaohui Yan, Peng Gao, Yi Wu, Dapeng Wu, Yanshuo Li, Qiankun Qiu

Publikováno v: Chromatographia. 84:549-557

In this study, freestanding fully porous polyimide (FFPP) membranes were prepared in batches by the scraping technique and vapor-induced phase separation (VIPS) and used for thin film microextraction (FFPP-TFME). When water vapor was applied simultan

Porous electrospun microfibers for low flow-resistant solid phase extraction of fluoroquinolones in tap water, egg and milk samples

Autor: Jiulong Li, Yanshuo Li, Xiaohui Yan, Dapeng Wu, Qiankun Qiu, Yuanbo Chen, Yi Wu

Publikováno v: Journal of chromatography. A. 1661

In this work, porous electrospun microfibers (PEMFs) were prepared using a polyimide/polyvinylpyrrolidone/polyethylene glycol (PI/PVP/PEG) solution mixture with coaxial ultrasonic water vapor spraying. After removing PVP and PEG by ultrasonic water w
