Interdigitated 65 pairs of generator / collector electrodes set off electrochemical RedOx cycling continuously as shown in Fig. 1. This reaction significantly boosts sensitivity of the electrode. Furthermore, samples are preserved when Dual (Red-Ox) Mode is chosen - Not like as Single Mode eats up samples at measurements.

IDA Electrode - Structure

Fig. 3 shows voltammograms of ferrocene samples ((a),(c): 10 µL , (b),(d): 0.2 µL) using IDA electrode ((a),(b): Dual mode; (c),(d): Single Mode). As they indicate, measuring mode makes obvious difference on their responses. Dual mode reinforces reduction current at collector electrodes with increase of oxidation current at generator electrodes. At the measurement (d), response is scarcely obtained because the sample was consumed during the experiment.

Figure in right shows wire assembly of connecting cable.

 

In order to avoid abrasion on a connector part of the electrode, please insert and remove it according to the following order:

[IDA Electrode Setup Sequence]

(1)Put the IDA electrode into the connector
(2)Insert the white color electrode fixer into the connector

[IDA Electrode Remove Sequence]

(1)Remove the white color electrode fixer from the connector
(2)Remove the IDA electrode from the connector
