A combined single electrochemical sensor designed to measure synchronously and transcutaneously oxygen partial pressure and carbon dioxide partial pressure (RADIOMETER prototype) was applied onto the scalp in 21 fetuses during labor. The values of tcPo2 respectively tcPco2 were compared with the values of fetal blood analysis (FBA) and blood from the umbilical artery (UA): Comparing the tcPco2 ...

I evaluated a commercial electrochemical method (Environmental Science Associates), based on potentiostatic coulometry, for determining iron and total iron-binding capacity (TIBC). The method requires 25 and 100 microL of serum, respectively, for these measurements. Serum iron concentrations so determined in 99 normal volunteers satisfactorily correlated with those determined by the Iron Panel ...

In this paper, a new approach to the computation of electrochemical impedance spectroscopy (EIS) is presented where the EIS system is represented by a convolutional model, and thus the impedance of the EIS system is computed using robust deconvolution algorithms. Very promising results are obtained .

• CTD probes are the preamble for current in-situ seawater monitoring. Relevant species to measure in seawater: trace metals, nutrients and carbon species. Electrochemical sensors last five years analysis. Lack of applications. Learning from panorama advance field. In water monitoring panorama, certain benefits expected arise when modus operandum analysis shifts sampling-based purely approaches...
