Electrochemical sensors are an integral part of our daily lives, making up the largest percentage of all chemical sensors. The sensing mechanisms are based on various electrochemical detection methods, ranging from amperometry to electrochemical impedance analysis. Many of the applications are biochemical and biomedical, where the more generic term, biosensors is often used. The most well-known, and arguably the most impactful, electrochemical sensor to date is the self-monitoring blood glucose meter used to assist diabetics in controlling their blood glucose levels.
The range of applications where electrochemical sensors are in use and/or under development is far reaching. Some examples include gas sensors, such as those used in homes to detect CO, heavy metal sensors for water quality analysis, and hydrocarbon, alcohol, and ketone sensors for measuring motor oil degradation. Additional examples where electrochemical sensors have been applied, include:
Biological/Chemical Warfare (Homeland Security)
- Food Monitoring
- Medical Diagnostics
- Home/Environmental Monitoring
Regardless of the method of detection, the development and utilization of these as transducers continue to expand. Design and optimization of any electrochemical sensor begins with a proof of concept, followed by prototype development, scale-up and commercialization. Both Princeton Applied Research and Solartron Analytical offer the capabilities and performance required for each step in this process. Whether it be the low current measurement capabilities for determination of the minimum detection limit, such as that provided by the VersaSTAT 4 or the EchemLab XM, or a multi-channel platform for high throughput analysis, such as that available within the PARSTAT MC product line, Princeton Applied Research and Solartron Analytical instruments have the tools researchers need to develop and refine these life-enhancing devices.
