5 Operating in CI Mode

General Guidelines

116 5977C GC/MSD Operating Manual

General Guidelines

• Always use the highest purity methane (and other reagent gases, if

applicable). Methane must be at least 99.9995% pure.

• Always verify the MSD is performing well in EI mode before switching to CI.

(See “To Verify EI System Performance” on page 104.)

• Ensure the CI source and GC/MSD interface tip seal are installed.

• Ensure the reagent gas plumbing has no air leaks. This is determined in PCI

mode, checking for m/z 32 after the methane pretune.

• Ensure the reagent gas inlet line is equipped with gas purifiers (not applicable

for ammonia).
