要約(英語): In this study, we carried out a simultaneous measurement of the negative ion mobility and the H2O concentration in different purities O2 using a high pressure ion drift tube for an investigation on effects of impurities. We used four different purities O2 as ultrahigh-purity (99.99995% with a gas purifier), high-purity 1 (99.99995%), high-purity 2 (99.9999%) and low-purity (99.9%). The H2O concentration in ultrahigh-purity O2 through the chamber equipped the ion drift tube was monitored between 15 to 100 ppb although the gas purifier could be removed the H2O concentration less than 100 ppt because of an outgassing from the inner surfaces of the chamber, ion drift tube and so on. In contrast, the ion mobility was observed as a constant value of 2.39 cm2/V・s as O4-. Then, a mobility 2.31 cm2/V・s was observed in high-purity 1 and 2 of which the H2O concentrations were 500 and 550 ppb, respectively. An interest result was found in low-purity O2 that is two mobilities 2.41 and 2.50 cm2/V・s corresponding to CO4- and N2O2- were measured in the H2O concentration between 400 to 580 ppb. One of the reasons considered as the effects of CO2 and N2 contained in O2.
