Abstract:
Isopropyl alcohol (IPA) was used to "clean" instrument parts. Residual IPA interfered with the instrument Level 1 requirements. Subsequent helium purging did not reduce IPA concentrations to acceptable levels. Determine what "cleaning" means within the context of the requirements. Following bakeout to remove cleaning agents, retest over an extended period to assure that concentrations are not increasing as trapped quantities are released.
