Continuous flow analysis of mercury using a chalcogenide glass ion-selective electrode

Flow Injection Analysis of Mercury Using 4-(Dimethylamino) Benzaldehyde-4-Ethylthiosemicarbazone as the Ionophore of a Coated Wire Electrode

“…Although the detection limit of other Hg(II) ISE in FIA systems [23,29] are relatively the same as that obtained with the proposed mercury(II) ISE, the latter has a wider linear range (Table 4). …”

“…The sensitivity, selectivity and peak heights of a CWE in FIA system depend significantly on the membrane composition, specifically plasticizers [23]. However, the use of plasticized PVC membranes in a CWE has some disadvantages.…”

Kinetic Monte Carlo Simulations and Molecular Conductance Measurements of the Bacterial Decaheme Cytochrome MtrF

“…It was found that release of Hg from the electrode membrane is a minor contributor to the elevated Hg readings, which were attributed to the matrix effects of seawater 11. Matrix interferences do not preclude the use of chalcogenide glass electrodes for seawater analysis, though proper calibration or measuring procedure that would take into account matrix effect is necessary 11, 12. It is important to note that the mercury‐selective electrode was capable of distinguishing the two estuarine water samples and to show, as predicted, that the Hg 2+ activity was lower in nearshore samples than in the contaminated ones.…”

Sensor systems, electronic tongues and electronic noses, for the monitoring of biotechnological processes

“…Situation with artiWcial sensors is diVerent. For example liquid sensors usually have lower detection limits, which can in some cases go down to ppb or even ppt levels [e.g., 47,48], and higher selectivity compared to the gas ones. Evidently, despite the names "nose" and "tongue" both instruments are applicable to the measurements in the inedible or toxic environments.…”
