“…The World Anti-doping Agency has prohibited the oral use of SAL, and a concentration of more than 1000 ng/mL in urine is considered as an indication of doping (Pichon, Venisse, Krupka, Perault-Pochat, & Denjean, 2006). Quantitative detection of SAL currently is limited to instrumental methods, high-performance liquid chromatography (Cooper & Shepherd, 1996;Halabi, Ferrayoli, Palacio, Dabbene, & Palacios, 2004;Maudens, Zhang, & Lambert, 2004;Mazhar & Chrystyn, 2009;Murtaza, Ahmad, & Akhtar, 2009), gas chromatography-mass spectrometry (Tanaka, Yoneda, Inoue, Sugiura, & Ueno, 2000;Zhang et al, 2006), capillary electrophoresis (Chen, Wang, Duan, Chen, & Chen, 2005;Chu, Geng, Zhou, & Ye, 2007;Felix et al, 2006), etc. Most of these methods share a number of important drawbacks.…”
