Are there any field applicable phosphate sensors available?

I haven't been able to find a "field applicable" phosphate sensor in the market yet. Seems there are many unsolved challenges such as longevity, signal drift, selectivity, etc for this sensor in...

Effect of porous electrode on electrochemical sensor current density?

If the available surface area for an electrochemical reaction increases, current would go up and according to electrochemical kinetics current density should stay constant. Is it possible that...

For an electrode reaction, how can we experimentally make sure whether the system has hit the mass transport limit (methods other than E-i wave)?

In an electrochemical reaction O+ne=R, in the anodic direction (R->O+ne), above a certain level of applied potential, system hits the mass transport limit. Then, bulk concentration of O won't...

In modeling electrochemical impedance spectroscopy (EIS) data, when do we connect the EC components in series and when in parallel?

I have some EIS data of corroded cast iron coupons in NaCl solutions. I want to model my data by taking into account two components. A charge transfer layer and a porous layer. For both of these...

How do you evaluate localized forms of corrosion as a function of time with electrochemical techniques?

I've read about the pitting onset potential in polarization curve, other than that, is it true to contend that electrochemical techniques (such as impedance or polarization) are just limited to...
