Important points about the CI MSD to cover include:
•
Cleanliness is the most important factor for success in CI,
especially negative mode. This includes air leaks, water, and
residual PFDTD calibrant.
•
NCI reagent gas setup:
There are no negative reagent ions formed. To set up for NCI
mode, tune in PCI mode, then load NCI tune file to switch
parameters, set gas flow to 40%; adjust if necessary for
specific analyte.
•
NCI operation:
Reagent gas flow, source temperature, and emission current
are the three most important parameters for optimizing NCI.
•
No PFDTD calibrant ions are formed in PCI with isobutane or
ammonia. Tune with methane, and copy parameters to new
file: e.g., PCINH3.U.
•
The gas purifier can not be used with ammonia.
•
Must ballast foreline pump daily if running ammonia. Refer
to the maintenance chapter of the 5973 inert MSD Hardware
Manual.
