An enzyme-assisted and nitrogen-blowing salt-induced solidified floating organic droplet microextraction for determination of clenbuterol and ractopamine in swine feed via capillary electrophoresis

Supramolecular recognition enhanced electrochemical sensing: β-cyclodextrin and Pd nanoparticle co-decorated 3D reduced graphene oxide nanocomposite-modified glassy carbon electrode for the quantification of ractopamine

“…At present, various analytical techniques, including enzyme-linked immunoassay, 7 immunochromatography, 8 chromatography, 9 electrophoresis, 10 fluorescence, 11 and electrochemiluminescence, 12 have been reported for the detection of RAC. Notwithstanding their efficacy, these strategies are beset by time consumption and the need for costly instrumentation, skilled technicians, and pretreatment processes.…”

Mixed mode monolithic sorbent in pipette tip for extraction of ractopamine and clenbuterol prior to analysis by HPLC-UV and UHPLC-Q ExactiveTM Plus Orbitrap MS

“…Several techniques including high-performance liquid chromatography-ultraviolet detection (HPLC-UV) (Qiu et al 2016;Xu et al 2010;Zhu et al 2014), liquid chromatography-tandem mass spectrometry (LC-MS/ MS) Shao et al 2009;Wang et al 2017;Wang et al 2016aWang et al , 2016b, capillary electrophoresis (Chen et al 2008;Wang et al 2015;Wang et al 2010), electrochemical method (Wu et al 2012), Raman spectroscopy (Xiao et al 2015;Zhai et al 2012), and colorimetric detection (He et al 2011;Zhou et al 2013) have been developed for the analysis of these compounds in various kinds of samples, such as pork (Qiu et al 2016;Wang et al 2016aWang et al , 2016bXu et al 2010), pig liver (Shao et al 2009;Zhu et al 2014), swine urine (He et al 2011;Wang et al 2017;Zhai et al 2012), and animal feeds (Wang et al 2015;Wang et al 2010;Wu et al 2012;Zhou et al 2013).…”

Enhancing a clenbuterol immunosensor based on poly(3,4-ethylenedioxythiophene)/multi-walled carbon nanotube performance using response surface methodology

“…In previous studies, a few methods were developed to detect and monitor antibiotics including CLB such as microbiology assay, enzyme-linked immunosorbent assay (ELISA), 5 high performance liquid chromatography (HPLC), 6,7 liquid chromatography-mass spectrometry (LC-MS), 8 gas chromatography-mass spectrometry (GC-MS), 9 capillary electrophoresis, 10,11 surface plasma resonance 12 and electrochemical 13 methods. However, even though analytical methods such as HPLC, LC-MS and GS-MS are very sensitive and effective, these methods are relatively expensive, time-consuming and unsuitable for on-site monitoring due to the use of large instruments.…”
