Chem., 2001, 508(1-2), 41–47. By gradually increasing the rotation rate of the RDE, the rate of mass transport of the dissolved oxygen to the electrode surface increases. Initially, the cathodic (reduction) current at the disk electrode is governed by this mass transport (i.e., the rate at which oxygen is arriving at the electrode). As the rotation rate increases, the current increases as the amount of oxygen arriving at the electrode surface increases.

4Practical Matters

Rotating Ring-Disk Koutecky-Levich Series (KL-RRDE) and RRDE Collection experiments,

4.1Polishing Electrodes

4.2Coating Catalyst on Disk Electrode
4.3Rotation Rates
![](https://pineresearch.com/dev/shop/wp-content/themes/pine-research/images/tooltip-violet@2x.png)
Rotating Ring-Disk Koutecky-Levich Series (KL-RRDE) Be sure that the RDE being used is rated for this range of rotation rates. For the RRDE Collection experiments, a rotation rate between 1500 and 2000 RPM is generally sufficient. Again, be sure to check the range of allowable rotation rates for the particular RRDE being used.
4.4Collection Efficiency
![](https://pineresearch.com/dev/shop/wp-content/themes/pine-research/images/tooltip-orange@2x.png)
Theoretical Determination of Collection Efficiency (N) not all the product generated at the disk electrode will make the trip to the ring electrode. The flow pattern at a rotating electrode generally sweeps anywhere from 20% to 30% of the disk products past the ring electrode. The percentage of material which is collected (detected) at the ring electrode is often called the collection efficiency of the RRDE.

Sometimes this damage (usually a leak) can be repaired by replacing the PTFE spacer between the disk and the ring electrode. This piece is called the PTFE U-Cup,
