There is various potentially hazardous aerosol suspended in atmospheric air, such as virus, exhaust gas, PM 0.1 and 2.5, endospore of bacteria, etc. One of the important issue is a monitoring technology to protect from such the hazardous aerosol from out living sphere. For this purpose, we have tried to develop a sampling mechanism, which is suitable for longtime continuous monitoring purpose. In this work, we have proposed and experimentally demonstrated new sampling method, which was utilized with liquid-gat. By testing the device using a carbon toner as a model of carbon particulate in atmospheric air, we confirmed that the liquid-gate sampling worked successfully.
