IDA (Interdigitated Array) Electrode 10 µm

Genaral configuration for the IDA electrode:

Cyclic Voltammetry Measurement using IDA Electrode

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.

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.

New product line without passivation membrane

IDA Electrode Connecting Cable kit

This device is used as a substituting item of a connecting part of IDA Electrode.

Please treat IDA Electrodes with care especially when you insert and remove them since it consists of quartz glass.

If you had a difficulty in setting up of an IDA Electrode into a connector at the cable, loosening the four grippers of the connector (shown in Figure below) with a tweezer would work.

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

Click

[IDA Electrode Remove Sequence]

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