To remove the source components from the ion block:
1. Remove the source enclosure (see page 28).
2. To remove the gas cone and PEEK cone clamp, pull the cone clamp away from the
instrument.

3. Remove the sample cone assembly from the right-hand side of the ion block, and
disassemble the parts by hand.
Notes:
• Three parts compose the sample cone assembly: a metal sample cone; a disc aperture
assembly; a metal entrance-aperture carrier.
• The disc aperture assembly contains a metal disc. If the disc becomes separated from
the rubber carrier, simply re-insert the disc into the carrier.
Requirement: The Standard and Performance QDa Detectors require different entrance
aperture discs. When ordering a replacement entrance-aperture disc and seal, ensure that
the entrance-aperture disc is the correct type.
Warning: To avoid burn injuries, allow the ion block to cool before performing this
procedure.
