Simultaneous and Direct Determination of Vancomycin and Cephalexin in Human Plasma by Using HPLC-DAD Coupled with Second-Order Calibration Algorithms

<table>Normalized UV-Vis spectral profiles were resolved by the SWATLD in human plasma. Solid and dotted lines represent the UV-vis spectral profiles of vancomycin, cephalexin, and interference. The medium dash denotes the actual vancomycin and cephalexin.</table>
