We demonstrate in-situ measurement of the photooxidization process of alkanethiol self-assembled monolayers using a Dual-channel Quartz Crystal Microbalance (D-QCM) sensor that uses spherically contoured resonators to acoustically separate sensing channels for simultaneous compensation of environmental disturbances. Using a photolithographic method to make the D-QCM, the reference channel used in parallel with the sensing channel has almost the same resonant frequency and temperature coefficient of frequency. As a result, mass changes of 10-pg order accuracy were observed under strong ultraviolet radiation over 4 days. Using the D-QCM, we can success to measure photoconversion from thiolate to sulfonate during UV irradiation
