2-2 Preparing for Operation
Starting the instrument
Starting the instrument entails powering-on the workstation, logging into the
workstation, powering-on the 3100 Detector and all the other instruments,
and starting the Empower or MassLynx software.
Requirement: You must power-on and log in to the workstation first to ensure
that it obtains the IP addresses of the system instruments.
To start the instrument
1. Ensure the nitrogen supply is connected to the instrument’s API gas
connection.
Requirement: The nitrogen must be dry and oil-free, with a purity of at
least 95%. Regulate the supply at 600 to 690 kPa (6.0 to 6.9 bar, 90 to
100 psi).
For more information on connections, see the figure “Instrument rear
panel” on page 1-9.
2. Power-on the HPLC system workstation, and log in before powering-on
the other instruments.
3. Press the power switch on the top, left-hand side of the instrument and
HPLC instruments. Each system instrument “beeps” and runs a series
of startup tests.
Caution: Using incompatible solvents can cause severe damage to the
instrument. Refer to Appendix C, “Materials of Construction and
Compliant Solvents”, for 3100 Detector solvent information.
Warning: During analyses that require flammable solvents, to avoid
ignition of the solvents, never let the nitrogen supply pressure fall
below 690 kPa (6.9 bar, 100 psi).
