摘要
A column-switching, reversed-phase high-performance liquid chromatographic (HPLC) assay for a new structurally unique carbapenem antibiotic, ertapenem, in urine has been improved for selectivity and automated using a Packard MultiPROBE(R) II EX pipetting station. The method uses column-switching for on-line extraction of the urine sample. The extraction column, analytical column, mobile phase, and timing of the column-switching valve have been changed to enhance selectivity for the analyte over endogenous background material. Sample transfer and dilution prior to direct-injection into the HPLC system have been accomplished using a Packard MultiPROBE(R) II EX robotic liquid handling system. (C) 2002 Elsevier Science B.V.
