Interdigitated Ring Array (IDRA)
SKU: N/A
Category: Thin-film Electrochemical Sensors
Metal-based Interdigitated Ring Arrays (IDRA) are fabricated using thin-film technologies on a glass substrate.
- Four-electrode configuration featuring two radial arrays of interdigitated working microelectrodes.
- IDRA electrodes can be used in single- or dual-mode.
- Specifically designed for use in flow systems.
InterDigitated Ring Arrays (IDRA) are available in gold or platinum. A standard SU8/PI resin protective layer is used to define the electrochemical cell, allowing for the use of very small sample volumes. IDRAs are also available without this passivation layer upon request. Choose the option that best fits your experimental needs.
