| Abstract: | During thermal vacuum tests, contaminants are collected and their compositions are analyzed. The witness plate is used to collect deposits, which is then solved by acetone. The solution is analyzed using GC/MS to identify constituents of the contaminants. Main contaminants in satellite thermal vacuum tests and solar array thermal vacuum tests are identified as phthalate and siloxane, and their effects are analyzed. |
