Determination of tetracyclines in human urine samples by capillary electrophoresis in combination with field amplified sample injection.

Posted on 9 November, 2017 by fqm302

A sensitive method using CZE‐UV detection has been developed for the determination of five tetracycline antibiotics in human urine samples. To improve the sensitivity of the method, an on‐line preconcentration strategy, named field‐amplified sample injection, has been developed, based on … Continue reading →

On-line preconcentration strategy for the simultaneous quantification of three local anaesthetics in human urine using capillary zone electrophoresis

Posted on 15 December, 2015 by fqm302

The simultaneous determination of usually employed anaesthetics (procaine, lidocaine and bupivacaine) has been developed and validated using capillary electrophoresis with ultraviolet detection at 212 nm. The separation of these three drugs has been achieved in less than 7 min, using … Continue reading →

Dispersive liquid-liquid microextraction prior to field-amplified sample injection for the sensitive analysis of 3,4- methylenedioxymetamphetamine, phencyclidine and lysergic acid diethylamide by capillary electrophoresis in human urine

Posted on 13 November, 2012 by fqm302

A novel capillary zone electrophoresis (CZE) with ultraviolet detection method has been developed and validated for the analysis of 3,4-methylenedioxymethamphetamine (MDMA), lysergic acid diethylamide (LSD) and phencyclidine (PCP) in human urine. The separation of these three analytes has been achieved … Continue reading →
