Distinction
Hydrodynamic technique are distinct from still and unstirred experiments such as cyclic voltammetry where the stead-state current is limited by the diffusion of substrate. Experiments are not however limited to linear sweep voltammetry. The configuration of many cells takes the substrate from one working electrode across another, RRDE for example. The potential of one electrode can be varied as the other is held constant or varied. The flow rate can also be varied to adjust the temporal gap the substrates experiences between working electrodes.

Famous quotes containing the word distinction:
“What! Would you make no distinction between hypocrisy and devotion? Would you give them the same names, and respect the mask as you do the face? Would you equate artifice and sincerity? Confound appearance with truth? Regard the phantom as the very person? Value counterfeit as cash?”
—Molière [Jean Baptiste Poquelin] (1622–1673)
“There is nothing more likely to drive a man mad, than the being unable to get rid of the idea of the distinction between right and wrong, and an obstinate, constitutional preference of the true to the agreeable.”
—William Hazlitt (1778–1830)
“Let those talk of poverty and hard times who will in the towns and cities; cannot the emigrant who can pay his fare to New York or Boston pay five dollars more to get here ... and be as rich as he pleases, where land virtually costs nothing, and houses only the labor of building, and he may begin life as Adam did? If he will still remember the distinction of poor and rich, let him bespeak him a narrower house forthwith.”
—Henry David Thoreau (1817–1862)
