Cleaning the APGC ion chamber
Required materials
• Chemical-resistant, powder-free gloves
• Combined, 2.5-mm Allen wrench and cone extraction tool
• HPLC-grade (or better) methanol
• Lint-free tissue
To clean the APGC ion chamber:
1. Prepare the instrument for working on its source (see page 2-2 ).
2. Remove the APGC ion chamber (see page 2-21 ).
3. Apply methanol to the lint-free tissue, and use it to carefully clean the
ion chamber.
4. Refit the APGC ion chamber onto the ion block (see page 2-9 ).
Warning:
To avoid personal contamination with biologically
hazardous, toxic, or corrosive materials, wear clean,
chemical-resistant, powder-free gloves when working with
probe and source components.
Warning:
To avoid burn injuries, take great care while
working with the source components, which can be hot.
Caution:
To avoid damaging the instrument by sudden
venting, do not open the source isolation valve at any time
while the APGC ion chamber is removed from the ion block
assembly.
