1.
Carefully fit the PEEK terminal block and ceramic heater mounting block, complete with
heater cartridge assembly, to the ion block.
2.
Use the combined 2.5-mm Allen wrench and cone extraction tool to tighten the captive
PEEK terminal block securing screw.
3.
Ensure that the grooves for the cover seal, cone gas O-ring, and isolation valve O-ring are
free from dirt and debris.
Tip:
If contamination is present, use 1:1 methanol/water, applied to a lint-free cloth, to
carefully clean the grooves.
4.
Fit the cover seal (a new one if you disposed of the old seal) to the ion block, ensuring that
it is correctly seated.
5.
Fit the cone gas O-ring (a new one if you disposed of the old O-ring) to the ion block,
ensuring that it is correctly seated.
6.
Fit the O-ring to the isolation valve.
Tip:
If you use a new O-ring, first soak it for several minutes in isopropyl alcohol, so that it
better fits the isolation valve.
7.
Fit the isolation valve to the ion block assembly, so that it is in the closed position.
8.
Fit the ion block cover plate to the ion block assembly, and then use the combined 2.5-mm
Allen wrench and cone extraction tool to tighten the two captive securing screws for the ion
block cover plate.
9.
Hold the sampling cone assembly so that the cone gas nozzle handle is oriented
horizontally and at the top, and then slide the sampling cone assembly into the ion block
assembly.
10. Grasp the sampling cone assembly handle, and use it to rotate the sampling cone
assembly through 90 degrees.
4.14.5 Fitting the ion block assembly to the source assembly
Required materials
• Chemical-resistant, powder-free gloves
• Combined 2.5-mm hex wrench and cone extraction tool
To fit the ion block assembly to the source assembly:
Warning:
To avoid personal contamination with biohazards, toxic materials, and corrosive
materials, wear chemical-resistant gloves when performing this procedure.
