Silicone Poisoning of Gas Sensors: MPS™ vs. Catalytic Bead
Silicone-containing compounds found in common products such as lubricants, vehicle detailing sprays, personal care products, and industrial sealants can poison catalytic bead (pellistor) gas sensors, causing them to lose sensitivity or become completely unresponsive to flammable gases—often without any indication of failure.
Watch this side-by-side demonstration to see how NevadaNano’s MPS™ Flammable Gas Sensor maintains accurate methane detection after silicone exposure, while a poison-resistant catalytic bead sensor becomes permanently deactivated.
Why Silicone Poisoning Matters in Flammable Gas Detection
A poisoned catalytic bead sensor may continue to display a normal zero reading in clean air, giving users a false sense of security even though the sensor can no longer detect dangerous flammable gas concentrations.
Unlike catalytic bead technology, NevadaNano’s MPS™ technology is inherently immune to silicone poisoning, maintaining reliable detection without protective filters or required field calibration.
