Quartz Sorption Sensors for Aceton Vapor
- 6 Downloads
The ratios between the film-sorbent parameters, sensitivity, and quartz sorption sensors’ sensitivity threshold have been obtained and analyzed. It has been demonstrated that, for the sorption sensors of vapors and gases based on polymer films, there exists a range of optimal values of thickness caused by its effect on the elastic properties. For acetone vapor sensors with a film made of polymethyl methacrylate (PMMA), this range is equal to 0.4–0.6% of the sensor’s plate thickness at the film deposition on both sides of the plate.
