“…LC-FLD gives better sensitivity and selectivity than LC-UV, as this technique is specific towards compounds exhibiting fluorescence properties (fluorophore). While some chemical food contaminants such as fluoroquinolones (McMullen, Schenck, & Vega, 2009) exhibit natural fluorescence properties, some other compounds require a derivatization step (addition of a fluorescent moiety) to enable detection in LC-FLD (Kijak, Jackson, & Shaikh, 1997;Vassilakis, Tsipi, & Scoullos, 1998;Dall'Asta et al, 2004). Numerous chemical contaminants have been monitored by LC-FLD such as mycotoxins (Trucksess et al, 2007), bisphenol A form PVC food packaging (Lopez-Cervantes & Paseiro-Losada, 2003), or veterinary drug residues (Ali et al, 2000;Edder et al, 2002).…”
