Starting Up the System after a Shutdown
To start up the LTQ Orbitrap XL after it has been shut down, you need
to do the following:
1. Start up the instrument
2. Set up conditions for operation
Note The recirculating chiller and data system must be running before
you start up the instrument. The instrument will not operate until
software is received from the data system. ▲
Use the following procedure to start up the LTQ Orbitrap XL:
1. Start up the (optional) LC and autosampler as is described in the
manual that came with the LC and autosampler.
2. Start up the data system and the chiller.
3. Turn on the flows of helium, nitrogen, and argon at the tanks, if
they are off.
4. Make sure that the main power switch of the LTQ XL is in the On
position and the electronics service switch of the LTQ XL is in the
Operating position.
5. Place the main power switch at the right side of the
LTQ Orbitrap XL in the On position.
6. Put the Vacuum Pumps switch to the ON position. See Figure 1-7
on page 1-9. The rotary-vane pumps and the turbomolecular pumps
are started.
Note Pumping the system after a complete shut down takes hours and
requires overnight baking of the system. ▲
