Disassembling the source ion block assembly

Required materials

• Chemical resistant powder gloves
• Combined 2.5-mm hex wrench and cone extraction tool
• O-ring removal kit

To disassemble the ion block assembly:

Warning: To avoid personal contamination with biologically hazardous, toxic, and corrosive materials, wear chemical-resistant, powder-free gloves when performing this procedure.

1. Ensure the source isolation valve is closed.

2. Grasp the cone gas nozzle handle, and use it to rotate the sampling cone assembly through 90 degrees.

3. Slide the sampling cone assembly out of the ion block assembly.

4. Use the combined 2.5-mm hex wrench and cone extraction tool to loosen the 2 captive screws securing the ion block cover plate.

Important: To ensure correct operation of the ion block assembly after reassembly:

• do not remove the sampling cone assembly retaining blocks.

• do not adjust the screws securing the sampling cone assembly retaining blocks.

5. Remove the ion block cover plate.

6. Grasp the isolation valve, and pull it out of the ion block.

7. Use the O-ring removal kit to carefully remove the isolation valve O-ring (see Removing O-rings and seals).

Warning: To avoid spreading contamination with biologically hazardous, toxic, and corrosive materials, dispose of all waste materials according to local environmental regulations.

8. If the isolation valve O-ring shows signs of deterioration or damage, dispose of it in accordance with local environmental regulations.

9. Use the combined 2.5-mm hex wrench and cone extraction tool to loosen the captive PEEK terminal block securing screw.

 Notice: To avoid damaging the heater cartridge assembly wires, do not bend or twist them when removing the assembly and ceramic heater mounting block from the ion block.

10. Carefully remove the PEEK terminal block and ceramic heater mounting block, complete with heater cartridge assembly, from the ion block.

Tip: You can invert the ion block assembly to facilitate this process.

11. Use the O-ring removal kit to carefully remove the cover seal from the ion block (see also Removing O-rings and seals).

12. Use the O-ring removal kit to carefully remove the cone gas O-ring from the ion block.

Warning: To avoid spreading contamination with biologically hazardous, toxic, and corrosive materials, dispose of all waste materials according to local environmental regulations.

13. If the cover seal or cone gas O-ring shows signs of deterioration or damage, dispose of it in accordance with local environmental regulations.
