Locating Tools and Supplies
You will need the following equipment when maintaining the ion lenses:
• Safety glasses
• Pure water
• 2% detergent solution
• Methanol (HPLC grade) or acetone (EL grade) for cleaning the tools
• Polishing paper (#400, #1200 grit P/N: G1833- 65404)
• Laboratory gloves
• Allen wrench (included in the tool kit)
• Jewel driver (Phillips)
• Ultrasonic bath
• Ohm meter
• Laboratory tissue
• Screwdriver (included in the tool kit)
• Alumina abrasive powder (P/N: 8660- 0791)
• Glass beaker (large/small)
• Tweezers
• Cotton swabs (P/N: 9300- 2574)
• Plastic tray
* Use clean and degreased tools.
* Use close- fitting laboratory gloves that are powder free and tolerant for
handling organic solvents (methanol).
NOTE
Pure water used for cleaning is indicated as water that has been generated using the
ion-exchange method and a membrane filter, and has an electrical resistance of at least
18 MΩ.
CAUTION
Do not allow the parts in the vacuum chamber to become stained in any way. Always
use clean laboratory gloves and handle the components in a contamination free place.
Avoid contaminating or damaging the O-ring and flange surfaces. Contaminants and
damage may cause the vacuum to leak.
