title: A sensitive high performance liquid chromatography microassay for bemoradan, a novel cardiotonic agent, in plasma/serum using a semi-automatic liquid/solid extraction sample preparation system--AASP.
abstract: A high performance liquid chromatographic method for the measurement of bemoradan levels in plasma/serum is described. This method uses Varian's AASP (Varian Associates, Sunnyvale, CA, USA), a semi-automatic liquid/solid extraction sample preparation system. It requires only small volumes of plasma/serum samples (0.2-1 mL) and needs no organic solvent for sample preparation. The mean recovery of bemoradan at plasma or serum concentrations of 0.5-100 ng/mL is 82%. The assay has a detection limit of 0.5 ng/mL (when 1 mL of plasma/serum is used) and is linear in the concentration range 0.5-500 ng/mL.
