Amperometry in chemistry is the detection of ions in a solution based on electric current or changes in electric current. Amperometry is used in electrophysiology to study vesicle release events using a carbon fiber electrode .
Chronoamperometry is typically carried out in unstirred solution and at the fixed electrode, i.e., under experimental conditions avoiding convection as the mass transfer to the electrode. On the other hand, voltammetry is a subclass of amperometry, in which the current is measured by varying the potential applied to the electrode.
Electrophysiology (from Greek ἥλεκτ, ēlektron, "amber" [see the etymology of "electron"]; φύσις, physis, "nature, origin"; and -λογία, -logia) is the branch of physiology that studies the electrical properties of biological cells and tissues.
Thus, factors that are of critical importance to quantitative amperometry, such as the surface area of the working electrode, completely disappear from amperometric titrations. The chief advantage over other types of titration is the selectivity offered by the electrode potential, as well as by the choice of titrant.
By Gram Slattery. WASHINGTON (Reuters) - U.S. President Donald Trump said he expects Elon Musk to find hundreds of billions of dollars of fraud and abuse at the Pentagon during an audit that the ...
If you are able to approach the dog, remember that a lost, sick, or injured dog can be easily frightened and behave unpredictably. Don’t make sudden unexpected moves toward a strange dog.
Roundworms, tapeworms, hookworms, coccidia, and giardia are parasites that can infest a cat’s digestive system and cause gas and fluid buildup, vomiting, a swollen abdomen, and other symptoms.
The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI). [1] If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber turn, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same ...
