2 Installation
This section describes the installation of the HPLC-Chip/Nanospray Upgrade Kit hardware.
Upgrade the HPLC-Chip Interface
1. While the LC/MS instrument is venting, remove and properly dispose of the following parts
from the HPLC-Chip interface:
• Counter Electrode – Use the supplied Hex Wrench (part number 8710-2623) to
remove the counter electrode. The set screw only needs to be loosened to remove
the counter electrode.
• Existing Top Plate – The existing top plate may or may not contain the IRM wick
used to introduce IRM compounds into the spray chamber. The new Top Plate will
contain the IRM wick but also has been modified to provide additional standoff
clearance for the high voltage spray shield.
The items circled in red are to be removed and discarded.
