Chamber purging is usually required in a gas sensing research, in order to make a perfect dry air condition (Relative Humidity/RH = 0%) in the chamber. Experimentally, it was found that RH of the cylindrical chamber (volume = 7.5 cm3) never touch 0% (only 32% and 4%) although it was purged by 100 and 300 sccm of synthetic air (consists of 20% O2 and 80% of N2). It was also obtained the same condition when N2 gas was used instead of synthetic air. Simulation approach using box-form chamber (volume = 9.6 cm3) shows that the combination of the diffusion-convection process of N2 gas is responsible for the results of chamber purging experiment instead of pure diffusion or pure convection.
