“…Table 3 summarizes published methods for the determination of K and NK in plasma and urine. As it can be observed, the LODs obtained using our method are lower than those reported by some authors [2,4,18,28,29,32], but higher than others [17,23,24,30,51]. Among these, the lowest LOQ using GC-MS was reported by Bairros et al [24] (0.5 ng/mL for both K and NK), while Parkin et al [23] achieved a LOD of 0.03 ng/mL for K and 0.05 ng/mL for NK in urine, yet using UHPLC-MS/MS.…”

“…Moreover, Harun et al [17] also reported lower LODs; nevertheless, they hydrolyzed the samples, turning the whole process more laborious and time consuming. In general, in the papers that report better LODs [17,23,24,30,51], higher sample volumes (1-4 mL) were used, and/or more laborious methods were described, including derivatization steps [24]. Liquid chromatography has been successfully applied in the quantification of K and metabolites in biological samples; however, its application potential is restricted to some extent due to higher solvent consumption and to the fact that the process is more time-consuming.…”

“…The recovery and extraction time of the present method is better than other methods (Table 4). LOD in the proposed method is similar to the previous studies (Dams et al 2002;Leong and Huang 2008;Shamsipur and Fattahi 2011;Ranjbari et al 2012;Kohler et al 2013;Fernández et al 2013;Meng et al 2015) (Table 4).…”

“…It has been used for various types of biological matrices (Li et al 2008;Xiong et al 2009;Mashayekhi et al 2010;Rezaee et al 2010a;Rezaee et al 2010b;Fernández et al 2013). DLLME could be combined with a variety of chromatography techniques such as Gas chromatography-Mass Spectrometry (GC-MS) (Leong and Huang 2008;Meng et al 2015), High Performance Liquid Chromatography (HPLC) (Ahmadi-Jouibari et al 2013;Fernández et al 2015) and capillary electrophoresis (Kohler et al 2013).…”
