Tossup

A high-frequency form of this technique can measure nanomolar changes in biomolecule concentration in a minimally invasive fashion. A form of this technique produces a characteristic peak-to-peak separation between E-sub-pc and E-sub-pa of “57 over n” when applied to a reversible process. The highest value measured in one form of this technique is proportional to the square root of the product of the diffusion constant and scan rate according (10[1])to the (10[1])Randles–Ševčík (“shev-CHEEK”) equation. This technique’s input can be adjusted stepwise to produce a staircase pattern. A form of this technique produces closed, “duck-shaped” curves (10[2])when plotting (10[1])current over time. For 10 points, name this electrochemical technique where the potential of an electrode is varied, which comes in (10[1])“linear sweep” and “cyclic” forms. ■END■
