YANG Liu, GUO Cheng-hai, ZHANG Guo-sheng, et al. Research on dehumidification of chemical sensors sample gas[J]. 2007, (1): 33-35. DOI: 10.13873/j.1000-97872007.01.011.
PSAI/ePTFE composited membrane is prepared.Vapor transfer rate of water and DMMP of different membrane is determined by static method.The PSAI/ePTFE membrane is selected to study the effect of dehumidification in the apparatus designed.At 19 ℃
reflux flow of purge gas is used air dried by silica gel.The humidity of sample gas reduces from 98 %RH to 42 %RH at the flow rate of 3.3×10
