A voltammetric-amperometric detector for liquid chromatography based on a dual electrode electrochem-ical cell has been developed. This detector enables voltammograms to be obtained without the charging current problems inherent in single electrode voltammetric detectors. The detector is operated by scanning the potential of the upstream (voltammetric) electrode and detecting the electrolysis p...

In this study, Malvasylvestris flower extract (MFE) was used as a corrosion inhibitor for carbon steel in 1 M HCl solution. Malvasylvestris extract was analyzed by gas chromatography coupled with a mass spectrometry detector (GC-MS). Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies revealed that the inhibition efficiency increases with increasing MFE concent...

Simultaneous acquisition of in vivo electrophysiological and neurochemical information is essential for understanding how endogenous neurochemicals modulate the dynamics of brain activity. However, up to now such a task has rarely been accomplished due to the major technical challenge of operating two independent recording systems simultaneously in real-time. Here we propose a simpler solution ...
