IDA(Inter Digitated Array) Electrode

Cyclic Voltammetry Measurement using IDA Electrode

IDA(Inter Digitated Array) Electrode

 

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

IDA Electrode - Structure

Fig.3 shows voltammograms of ferrocene samples ((a),(c):10µL , (b),(d):0.2µL) using IDA electrode ((a),(b): Dual mode , (c),(d): Single Mode). As they indicate, measureing mode makes obvious difference on their response. 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.

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

IDA Electrode Connecting Cable kit / Set Up



 

If you had a difficulty in setting up of an IDA Electrode into a connector at the cable, loosening the four grippers of the connctor(shown in a 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 accoring to the following order:

[IDA Electrode Set Up 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
