Multiresidue determination of sulfonamides in edible catfish, shrimp and salmon tissues by high-performance liquid chromatography with postcolumn derivatization and fluorescence detection

Multiresidue antimicrobial determination in Nile tilapia (Oreochromis Niloticus) cage farming by liquid chromatography tandem mass spectrometry

“…Some simple, clean and rapid extraction methods are based on solid-liquid extraction (Romero et al, 2007) or solid-phase extraction (Gehring et al, 2006;Zhu et al, 2001). A widely used method for screening analysis is immunoaffinity chromatography (Senyuva and Gilbert, 2010), but it shows little selectivity.…”

HPLC–DAD–FLD Determination of Veterinary Pharmaceuticals in Pharmaceutical Industry Wastewater with Precolumn Derivatization Using Fluorescamine

“…On the other hand, a fluorescence detector enables the determination of analytes at low concentrations in a manner similar to the mass spectrometer detector. analytes that are highly fluorescent like fluoroquinolones (FQ) are especially suitable for liquid chromatography analysis with fluorimetric detection [17][18][19][20][21][22].…”

Trends in Microextraction Techniques for Sample Preparation

“…The fluorescent detection was performed at 400 nm excitation wavelength and 495 nm emission wavelength. The mean recoveries for the spiked shrimp samples at three levels ranged from 67.3% to 90.5% [64].…”

“…In addition, lab-synthesized sorbents can be also applied. In this sense, researchers have proposed the use of MIPs [64] and ionic liquids intercalated in montmorillonite [65] as a sorptive phase in this device. Polyethylene disks, conventionally used as frits in solid phase extraction cartridges, can be also used as stirred units by simply piercing them with a metallic wire.…”
