Installing The Apgc Ion Chamber On The Mass Spectrometer's Ion Block - Waters APGC Operator's Manual Supplement

Installing the APGC ion chamber on the mass spectrometer's ion
block
Required materials
• Chemical-resistant, powder-free gloves
• Combined, 2.5-mm Allen wrench and cone extraction tool
• Dentist's mirror
Requirement:
mass spectrometer, you must use the reduced-aperture, 0.36-mm, sample cone
supplied with the APGC, to avoid problems associated with unstable signal
intensity.
To install the APGC ion chamber:
1. Select the correct sample cone for the instrument you intend to use with
the APGC:
• For Xevo TQD or SQ Detector 2 instruments, use the 0.36-mm
sample cone provided with the APGC. The cone is labelled "0.36mm"
on its base and side wall.
• For all other instruments, use the sample cone that you retained in
the previous procedure
2. Ensure that the O-ring is in position on the sample cone.
To avoid personal contamination with biologically
Warning:
hazardous, toxic, or corrosive materials, and to avoid
spreading contamination to uncontaminated surfaces, wear
clean, chemical-resistant, powder-free gloves when installing
the ion chamber.
To avoid burn injuries, take great care while
Warning:
working with the source components, which can be hot.
