A Quartz Crystal Resonator Modified with a Metal-Organic Framework for Sensing of Benzene, Ethylbenzene, Toluene and Xylenes in Water
Summary
A 10 MHz quartz resonator coated with a copper-based metal-organic framework detects BTEX compounds (benzene, toluene, ethylbenzene, xylenes) in flowing water. Frequency shifts are followed on several harmonics at once; differences between the 3rd and 5th harmonics tell the compounds apart, and the response time gives insight into how each molecule diffuses into the framework.
