multimode user guide and set-up guide.
To install the G1978B multimode source
If the multimode source is not already installed on your Triple Quadrupole
LC/MS, do these steps.
1 Install these parts from the multimode and APCI enablement kits that ship
with the G1978B multimode source into the Aux module on the Triple
Quadrupole LC/MS:
• APCI High Voltage Power Supply (p/n G1946-80058)
• Multimode HV board cable (p/n G1960-60858)
The Multimode Power Data cable is factory-installed on the 6460, 6490, and
6495.
2 Pour the electrospray tuning mix back into its original bottle or another
suitable container, rinse the calibrant bottle with acetonitrile, pour the
MMI-L tuning mix into the calibrant bottle, and attach the calibrant bottle
back onto the CDS.
3 Remove the electrospray source and install the multimode source:
a Put the nebulizer into the nebulizer adjustment fixture that is supplied
in the shipping kit. Check that the nebulizer needle is properly adjusted.
Make sure that the nebulizer needle is even with the end of the nebulizer
nozzle.
b Install the nebulizer in the spray chamber.
Do not install the G1960-65015 Multimode HV board on the 6460 or you can
damage the AJS ESI. The G1960-65115 Multimode HV board is already
correctly installed on the 6460 and is backward-compatible with the
G1978B multimode source.
