Gas Sorption of Acetone, Diethyl Ether, Toluene, Acetic Acid, and Ammonia on Plasma-Polymerized Hexamethyldisiloxane Films Coated with Quartz Crystal Microbalance

摘要

Recently, exposure to volatile organic compounds (VOCs), induced from building materials such as paint solvents from wall papers and artificial wooden floor, have been a serious problem to cause the multiple chemical sensitivity (sick house syndrome) [1, 2]. R&D known as conventional environmental monitoring method of exposure to VOCs concentration is important to sustain a safety human life space [3, 4]. Usually, the gas chromatography system and gas detector tube have been used for measurement of VOCs concentration. Although the GC method is highly precise, the price of the equipment is expensive [5].The gas detector tube is well-known method to detect gas concentration with inexpensive cost, and it is easy to operate. However, the gas detector tube can perform only one-time usage. Furthermore, this method has the risk of large experimental error to measure gas concentration [6]. Therefore we intend to develop high performance gas monitoring system using new gas sorption materials.
