How Does Sampling Sticky Gases Impact Gas Detection Equipment?
How sticky gases impact a gas detection device's response time.
A gas detection device's response time will be slower than normal when sampling a sticky gas because the tubing material interacts with the gas flowing along it, slowing down the overall flow of gas to the detector.
This behavior means that the actual gas concentrations might not be accurately measured, and the gas detection device won't alarm at the appropriate gas concentration, putting workers at risk for chronic and acute health effects.
Note: Gas adsorption by tubing may impact gas readings more during sampling than continuous monitoring. During continuous monitoring, gas levels at the sensor will eventually reach accurate or representative levels. During sampling, if the sample time is insufficient to compensate for a lower volume of gas at the sensor, gas readings may be inaccurate.
