Outgassing characteristics of ceramic, metallic, and polymeric filters
for H2O, O2, CO2, and CH4 were explored using APIMS. The outgassing d
ata have been normalized with respect to the parameters that varied fr
om one filter to the other. Hydrocarbon outgassing is also explored bo
th at room temperature from freshly installed filters and at elevated
temperatures. Polymeric filters appeared to be more transparent but di
d show hydrocarbon outgassing when heated to 50-degrees-C.
