IDA (Interdigitated Array) Electrode - 2 Ám

More fine IDA (Pt/Au) Electrode has been developed. Its 2 Ám pitch working electrodes significantly increase redox cycle and allow researchers to perform high-ultra-sensitive measurement.

Technical data concerning IDA Electrode 2 Ám

A CV curve obtained by 2 Ám IDA Electrode Au.
 

CV by Single mode

CV (Single) Using Au 2 um

  • Sample: 1 mM ferrocene methanol (0.5 M NaCl solution)
  • Mode: Single
  • Sweep Rate: 10 mV/s

CV by Dual mode

CV (Dual) Using Au 2 um

  • Sample: 1 mM ferrocene methanol (0.5 M NaCl solution)
  • Mode: Dual
  • Sweep Rate at G-Electrodes: 10 mV/s
  • Applied Voltage to C-Electrodes: -0.05 V
    Its collection efficiency was proved to be 97% by our calculation from limiting current of Collector electrodes and Generator electrodes.

Capture Efficiency

Compared with IDA Au 10 Ám and 3 Ám, the capture efficiency of the 2 Ám is higher, 93% for 10 Ám and 95% for 3 Ám.
For 2 Ám electrode, the limiting current of ferrocene methanol by CV Dual mode was 11 times as much as of the peak current by Single mode, while this ratio for 10 Ám and 3 Ám electrode were about 4 and 7.5, respectively. This means large increase of the redox cycle.
