A simple, rapid and precise LC method has been developed to determine the total concentrations of cefotiam (reported protein-binding ratios of 40–62%) in human serum. New procedures were incorporated in which proteins denatured by acetonitrile were dissociated from cefotiam. Macromolecular impurities above 30 kDa were entirely removed using an ultrafiltration membrane. The assay can be applied to...
A simple, rapid and accurate liquid chromatography method using ultrafiltration to pretreat cerebrospinal fluid (CSF) samples was developed to determine meropenem concentrations in human CSF in clinical settings. Meropenem in CSF samples was stabilized by mixing with 1 mol L−1 3-morpholinopropanesulfonic acid buffer (pH 7.0) (1:1). The mixture was transferred to a Nanosep 10 K centrifugal filter device;...
