Design of a Flow-Through Voltammetric Sensor Based on an Antimony-Modified Silver Electrode for Determining Lithol Rubine B in Cosmetics

<table>Hydrodynamic voltammogram obtained for Lithol Rubine B (1.50 ng) using the Sb/Ag detector. Stationary phase, HyperClone C<sub>18</sub> column (particle size 5-<i>μ</i>m, 250 mm × 4.6 i.d.); mobile phase, acetonitrile-water (30 : 70, v/v) containing 0.1 mM K<sub>2</sub>HPO<sub>4</sub> (pH 3.97); flow rate 0.5 mL/min.</table>
