“…In the literature there are some articles that describe this method for the quantification of FA in biological fluids (Hikal, 1983;Nawaz et al, 2014;Rahman, Hoffman, 1988;Sewell, Palmer, 1991;Sorense, 1988) and in pharmaceutical products (Ankam et al, 2010;British Pharmacopeia, 2010;Byrne, Velasco-Torrijos, Reinhardt, 2014Goswami, Gupta, Jogia, 2013;Hikal, Shibl, El-Hoofy, 1982;Hong, Rong, 2012;Peh, Tan, 2000;Nawaz et al, 2014;Nianfen, Yandong, Mooling, 2009;Shaikh et al, 2009). However, some of these methods are time consuming, have complex mobile phases, or require buffer solution, while others require long running times, high injection volumes and flow rates, or high FA concentrations in the sample.…”
