NeoCoat®-Analytics
Micro-electrodes chips Sensors
Thanks to our nanostructured diamond devices, NeoCoat can propose Microdisc array (MDA) or interdigitated array (IDA) of BDD electrodes for high performance analytical applications:
- Custom MDA of boron-doped diamond electrodes (microelectrode diameters in the range 2 to 10 micrometers): low flow dependence and increased signal-to-noise ratio thanks to the array arrangement
- Custom IDA of boron-doped diamond electrodes (finger distance of less than 5 micrometers): high redox cycling collection efficiency for sensitive electrochemical measurements and a wide dynamic range
- Chip size: standard 3x7mm or upon request
NeoCoat®-RDE set
NeoCoat offers a rotating disk electrode head, NeoCoat-RDE, based on NeoCoat-Electrodes. The electrodes consist of a polycrystalline boron-doped diamond (BDD) coating deposited on a silicon substrate. Such devices can be mounted on standard commercial RDE setups.
