Chitosan Coating on Quartz Crystal Microbalance Gas Sensor for Isopropyl Alcohol and Acetone Detection
Summary
A chitosan-coated QCM was simulated in COMSOL and tested with isopropyl alcohol and acetone vapours. Both model and experiment give a larger frequency shift for isopropyl alcohol (about 85 Hz against 42 Hz measured), which the authors relate to its higher molar mass and to hydrogen bonding between its hydroxyl groups and chitosan.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
