vac‑chip™ Assembly
The vac-chip assembly is comprised of the spraychip flange and the vac-chip flange. The
assembly is used to mount the vac-chip interface and parts of the ion optics to the source,
filter, and detector (SFD) assembly. The spraychip and vac-chip flanges, once assembled
together, generally remain so unless extensive cleaning is required.
The spraychip flange allows the connection of the microspray source to the SFD assembly
and provides the nebulizer gas connection to the spray source.
NOTICE
To fit the spraychip and vac-chip flanges together, refer to Spraychip Flange on page 60.
