Abstract


A passive (without a pump) sampler for electrostatically trapping particles suspended in the gas-phase was developed. The newly developed system is powered by AA size cell battery, which then converted to around 1300 V (DC). The system was tested in positive and negative charges by a combustion-made magnesium oxide as well as the outdoor particles. The particles suspended in the gas-phase were also measured by an online particle-sizer system. The collected particles were mainly measured by optical- and electron-microscopes, besides UV-Vis-NIR and XRF methods. The results show that the system is able to trap particles with size less than 1μm (submicron particles).
