Connecting the Forepumps to the LTQ XL MS Detector

Connecting the Forepumps to the LTQ XL MS Detector
6 LTQ Series Getting Connected Guide
Because the LTQ XL MS detector has a larger ion transfer tube than the LXQ MS detector, it
draws more ions into its ion trap and requires a second forepump to evacuate its skimmer
region.
To connect the forepumps to the LTQ XL MS detector
1. Using a hose clamp (P/N 00108-09001), connect the 3.8-cm (1.5-in.) ID reinforced
vacuum hose to the LTQ XL MS detector vacuum inlet. (The vacuum hose inlet is
located on the lower right side of the back panel of the LTQ XL MS detector.)
2. Connect the Tee (P/N 97055-20222) to the free end of the vacuum hose with a hose
clamp (P/N 00108-09001).
The ID of the TEE arms is 3.5 cm (1.375 inches). The OD of the TEE arms is 3.8 cm
(1.5 inches).
3. Using hose clamps (P/N 00108-09001), connect the 3.8-cm (1.5-in.) ID reinforced
vacuum hoses to the other branches of the Tee connector.
4. Connect a pump fitting adapter (P/N 00108-09005) to the free end of the vacuum hoses
with a hose clamp (P/N 00108-09001).
5. Place a centering ring (P/N 00108-02011) on the flange of each forepump vacuum inlet.
6. Connect the vacuum hose (with the attached fitting adapter) to the pump vacuum inlet.
Secure the hose to the pump using the KF20/25 vacuum hardware clamp
(P/N 00102-10020).
IMPORTANT For proper operation, the forepumps require an efficient fume exhaust
system. Most API applications contribute to the accumulation of solvents in the
forepumps. These solvents must be purged from the forepump oil periodically by
opening the ballast valve located on the top of the pump. Because opening the ballast
valve can release a large volume of volatile solvent waste, the fume exhaust system
must be able to accommodate the effluent resulting from periodic purging.
7. Use hose clamps (P/N 00108-09001) to connect the 2.5-cm (1-in.) ID blue exhaust hoses
from the forepump exhaust ports to the pump exhaust system in your laboratory.
Because the exhaust hose acts as a trap for exhaust fumes that would otherwise recondense
in the forepump oil, it should travel at floor level for a minimum of two meters (78.5 in.)
before it reaches the external exhaust system.
8. Connect the forepumps to line power:
a. Locate the Main Power circuit breaker switch on the power panel and switch the
circuit breaker to the Off position.
b. Connect the power cords attached to the forepumps to the forepump outlets located
on the power panel.
