Quinolones Reversed-phase LC is the first choice for the separation of quinolones; GC is not applied for this purpose due to the high polarity of these VDs. Certain ampholytic compounds, such as enrofloxacine and its TP, ciprofloxacin, can show peak tailing problems because of the presence of silanol groups and metal traces that interact with them. In consequence, the use of end-capped or high purity silica columns and the optimization of pH and ion-strength conditions are strongly recommended [4].

Figure 4. 8, 20 mM NH4Ac). ].
