METHOD AND DEVICE FOR MEASURING FILM PERMEABILITY OF ACID AND BASIC GAS

摘要: PURPOSE:To measure the permeability of a film by charging container whose opening part is covered with to be measured, solution salt which corresponds acid or basic gas, and detecting pH in means measurer equipped while brought into contact sample gas gas. CONSTITUTION:Through wall cylindrical 1, composite hydrogen ion electrode 3 inserted at lower-surface 4 measured fixed supporter 5 via o-ring 6. The 1 charged 2 that based e.g. NaHCO3 for gaseous CO2, NH4 NH3, NaHSO3 SO2. put vessel 10 spouted liquid 16 (water) from porous galss ball 13; stirred rotating stirrers (magnetic stirrer) 7 8, passes through reacts upon thereby measuring variation pH. sectional area, measurement time, solubility coefficient, etc., are substituted relational equations arithmetic find permeability.
