How Do Electrochemical Gas Sensors Work? | Nova Gas Analyzers

· If no target gas is detected, most electrochemical sensors indicate a reading of zero. However, unlike catalytic bead sensors, the sensor does require a balance or zero adjustment. While electrochemical sensors are designed to identify a specific gas, most demonstrate some degree of cross-sensitivity. This phenomenon refers to the response of ...

1 Electrochemical sensors

1 Electrochemical sensors These sensors employ redox reactions to quantify the amount of an analyte. The current flowing through the system or the potential difference between the electrodes as a result of the oxidation and reduction reactions involving the analyte are used for its quantification in the sample. The electrochemical sensors do not suffer from the drawbacks of optical sensors ...

Question: I have a customer who is using an electrochemical sensor for CO to comply with NIOSH Method 6604, however they are using Nitrogen instead of air as Zero Gas; they have Nitrogen for Gas Chromatography purposes. This Nitrogen has % purity. An ISO 17025 auditor told them that this could affect the calibration process for this sensor, so the customer is asking me if this is true.

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
