Ci Setup - HP 5973 MSD Hardware Manual

CI setup

In setting up your CI MD for operation in CI mode requires special care to avoid
contamination and air leaks.
General guidelines
• Before venting in EI mode, verify that the GC/MSD system is performing
correctly.
• Make sure the carrier gas plumbing and GC have no air leaks. (EI mode.)
• Make sure the MSD vacuum system has no air leaks.
• Make sure the reagent gas inlet line(s) are equipped with gas purifiers (not
applicable for ammonia.)
• Use extra-high purity reagent gases; 99.97% or better for methane and as pure
as is available for other reagent gases.
