An improved column switching high performance liquid chromatographic (HPLC) method was developed for determination of cetirizine in human plasma. Plasma samples were prepared by liquid-liquid extraction using methylene chloride. The samples extracted were initially injected into a clean-up Capcell Pak MF C8 column and the peaks of cetirizine and internal(More)
PURPOSE To determine small-field beam quality correction factors for several detectors used with flattened and unflattened beams of the Varian TrueBeam accelerator, and to quantify the clinical impact of these corrections through a treatment planning study. METHODS Small-field beam quality correction factors were measured and simulated in EGSnrc for(More)
