A simple and rapid ultra-high-performance liquid chromatography (UHPLC) method using UV detection was developed for the simultaneous determination of eight β-lactam antibiotics in human plasma including four penicillins amoxicillin (AMX) cloxacillin (CLX) oxacillin (OXA) and piperacillin (PIP) and four cephalosporins cefazolin (CFZ) cefepime (FEP) cefotaxime (CTX) and ceftazidime (CAZ). in gradient elution mode at a… Continue reading A simple and rapid ultra-high-performance liquid chromatography (UHPLC) method using UV
