There is a method for the calculation of the dielectric constantfrom the capacitance measured from the current intensity by theapplication of the alternative potential through the IDA electrode.
However, for an IDA electrode with a passivation membrane,
the capacitance of the membrane is also measured, making
impossible to obtain the exact measured value. For this purpose,
IDA electrode without passivation membrane was added to the

Technical note
The role of Counter electrodeSpectroelectrochemistry

For a system using three-electrode potentiostat, we measure current when a potential is applied between the working
electrode and the reference electrode. Passage of current through an electrical circuit requires electron transfer reaction
between the working electrode and the counter electrode. The main function of the counter electrode is to support asecond electron transfer reaction. Important parameter of the counter electrode is the surface area. It is required (area)large enough to support the current generated for the working electrode. For example, the surface area of the platinum
electrode of 5 cm length is sufficient to use as a micro-working electrode, such as steady-state cyclic voltammetry
experiments. However, for generating a high current measurements such as bulk electrolysis, the counter electrodeof a larger area is required, as Catalog No.012961 which the length of platinum is 23 cm. This electrode is used formeasurement, such as rotating ring disk.

Please confirm the newest information at ALS website
www.als-japan.com

Counter Electrodes

Others

The cell shape is also an important point. For the electrolysis, to avoid the contamination of the product from the counterelectrode, it is arranging separately, isolated in a chamber, from the working electrode. For electrochemical measurements
such as cyclic voltammetry, because of the short measurement time, you can ignore the effects of contamination byelectrolysis. Therefore, it is not usual the isolation of the counter electrode. In some cases, the separation of the counterelectrode in a chamber increases the resistance between counter electrode and reference electrode, under the influenceof (sintered glass) fritz. However, in the case of bulk electrolysis, because of long measurement time, the agitation andseparation of the working electrode and counter electrode using a chamber is necessary, to prevent the transportation
between two electrodes.

The dual glassy carbon electrode is considered to be astandard working electrode for cross flow cell. It is composed
for two glassy carbon electrodes, of 3 mm placed in series. Also
it could be rotated 90 degrees and applied as a parallel mode.
The selectivity improves with the application of dual series
electrode. In the parallel mode, identification of the substance,from the different applied voltage response ratio, is possible.
For the dual electrode, the electrode surface area doubles
by using the jumper connector, and high sensitivity analysis
becomes possible. For the working electrode, the platinum/goldelectrode and others are also available.

The quartz crystal microbalance (QCM) technique under coupling of electrochemistry and crystal oscillation is very useful to determine many compounds such as metal proteins, metal ions and thiol-conjugated oligonucleotides. The Resonance frequencyof quartz changes when material attaches to the electrode’s surface. This product is capable of super-micro quantitative analysis by using this unique behavior. However, for the best performance, use a degassed sample, to avoid bubbles.
QCMT Flow cell is reversible. With an inverted position of the blocks, it is possible to change from static to flow measurements.

Spectroelectrochemistry

Reference Electrodes

Spectroelectrochemistry (SEC) is aimed at the investigation of electrochemical reaction mechanism and the interface structure
between electrolyte solution and electrode. Remarkable progress in this field and related technology enables SEC to be
applied in wide areas. Nowadays, the relation between absorbance and potential for reversible or quasi-reversible systemis theoretically elucidated, on which basis the analysis of electrochemical characteristics becomes possible for the systemotherwise difficult with only the result of voltammogram. Typical example is redox enzyme cytochrome c and methylene blue.

Application

Comparison of 0.5 and 1.0 optical path length cell

The electrolysis time for the 0.5 mm optical path length cell is theoreticallya half, compared with the 1.0 mm cell. It is the opposite, for theconcentration, when the same result for the 1.0 mm cell is possible for ahalf of the concentration compared with the 0.5 mm cell. You could selectthe optical path length and the working electrode appropriate for yourresearch purpose.
For the comparison of 0.5 and 1.0 optical path length cell, sometimes a difference

Working Electrodes

The absorbance, at 420 nm, during electrolysis of the potassium ferrocyanide, in function of time, was investigated using 100,
250 and 500 µm thickness gasket. For the measured sample, using the 100 µm gasket, in 40 seconds the equilibrium wasshown (Fig.4-1). The 250 µm gasket was used for the monitoring of the electrolysis spectrum of the vitamin B12 derivativecomplex (Fig.4-2).

ITO (Indium Tin Oxide) electrode is generally used for spectroelectrochemical measurements. ITO electrode transmits the lightof the visible range, but do not transmit the light of ultraviolet range. The thickness of the ITO membrane is 100 ± 10 nm, andthe resistivity is 15 ± 1.5 Ω/sq*1.

Grid Electrode
Grid electrode is produced by the deposition of the platinum, gold or carbon onto the quartz glass. The dimension of the glass is 8 x 27mm, with a 1 mm of the thickness, and the grid line is 100 µm width with a distance of the 150 µm between lines.

ITO electrodeUnit: µm

The light transmittance was compared with ITO electrode and Gridelectrode (Au, Pt and Carbon) on a quartz glass as a reference. For ITO
electrode the light cannot be transmitted easily in an ultraviolet range. The
transmittance is about 10% at 280 nm of the wavelength. For wavelength
above 400 nm the transmittance is above 80%. Compared with the quartz
glass, the light transmission for grid electrode is about 30%, however it
could be used in an ultraviolet range.

OthersGrid electrode100

Reference data:
The light transmittance is 50 – 55% for SEC-C/C05 Platinum mesh electrode.

Polishing refreshes working electrode response
The purpose of the polish is to remove redox reaction products accumulated on the working electrode surface. The polishing
maintains a good condition of working electrode for CV/Flow cell.

before polish

Working Electrodes

after polishCounter ElectrodesWith repeated electrochemical redox reaction experiments, theadhesion of the experimental products onto the electrode surface
takes place and the electron transfer rate is attenuated gradually.
If the electron transfer speed becomes slow, the difference
between peak potentials for oxidation and reduction will broaden.

Glassy Carbon electrode
Upon refreshing the electrode surface by polishing, the electrontransfer rate will increase again. Consequently, the peakpotential difference becomes narrow and returns to an ideal CV.
