Audience: Engineers and product managers of electrochemical gas sensors who currently use absorption filters containing harmful lead acetate
The lifespan of an electrochemical gas sensor and its ability to detect problematic gases can be negatively impacted by an environment where interfering gases – such as H2S, SO2, HDMS and volatile organic compounds – are present. Gas absorption filters act as a gatekeeper between the interfering gases and the target gases of the sensor, enabling the target gas to reach the electrode and be identified. An interfering gas can decrease sensor performance over time and can trigger the sensor incorrectly. To safeguard the electrode from these interfering gases, manufacturers often use filters with lead acetate; however, lead acetate not only poses a threat to workers in direct contact but also can result in poor sensor performance over time. In this tech brief, learn how porous polymers can be used in absorption filters instead of lead acetate to make them safer for the environment and workers – and to enhance the sensor’s performance and lifespan.
