Electrochemical Sensors

Electrochemical sensors are a subclass of chemical sensors where the electrode is used as a transducer—converting a chemical response into a signal detectable by electrical instrumentation. Electrochemical sensors have been of increased interest in research and development for molecule detection in an array of fields from gas sensing to biomarker monitoring. The design of these electrodes is heavily dependent on the intended application, making material customization and configuration incredibly important factors in the development of new sensor technologies.

Prominent Sensor Application Fields:

  • Pharmaceutical Research and Development
  • Safety
  • Environmental Monitoring
  • Food Analysis
  • Medical Devices/Diagnostics

Screen printed electrodes are frequently used to develop electrochemical sensors and offer many advantages:

  • Economical
  • Highly selective
  • Easy to use
  • Low Volumes
  • Robust
  • Miniaturized size
  • High sensitivity

Metrohm offers not only a large catalog of screen printed and interdigitated electrodes for sensor development, but also flow cell accessories, potentiostat/galvanostats (both portable and stationary), and a range of spectroelectrochemical solutions.
