This study was carried out to investigate the collection Efficiency of mass in collector step at the different of physical gas characterization. This work has focused on the dependence of the collection efficiency of mass in the collector zone of a two-stage set up field with gas temperature T and the dew point tmeperature. To identify the dependence of the mass collection efficiency on the grounded plate of the collector zone M_P,k by the specific electric resistance of dust ρe and the relative humidity φ, 20 attempts have been made with three different gas temperature (50℃, 80℃, 110℃) at different dew point. At the specific electric resistance of dust ρe=10^6Ωm which relative humidity corresponds to φ> 15%, a easy rise of the grounded plate secluded dust mass share was measured again. As the result of the higher cohesion imprisonment power due to the adsorbtion of particle, the rise of the relative humidity developed on the particle surface. Therefore, the collection efficiency of mass was not predominant the high temperature T in the collector zone, neither was the pecific ellectric resistance of dust dependent.
