Review the Agilent 7890A Gas Chromatograph Operating
1
Guide (P/N G3430-90011) and the Agilent 5975 Series MSD
Operation Manual (P/N G3170-90036) for important safety
information and start up details before powering on your
instruments.
Verify that the split/splitless (S/SL) inlet septum, liner, and
2
O-ring are clean, properly installed, and in good condition.
3
Install a conditioned (HP-5ms 30 m x 250 µm x 0.25 µm)
column in the GC. Attach the column inlet to the S/SL inlet
and its outlet to the MSD transfer line. See the Agilent 5975
Series MSD Operation Manual for details.
4
Verify the EI ion source is installed.
5
Verify 99.9995% purity helium is attached to the carrier gas
supply of the S/SL inlet.
Power on the 7890A GC.
6
From the GC keypad, turn off the oven, Aux 2 heated zone
7
(GC/MSD transfer line), and inlet heater. If equipped, turn
off any GC detectors.
Before you turn on or attempt to operate the MSD verify the
8
following:
•
The vent valve must be closed (the knob turned all the
way clockwise).
•
All other vacuum seals and fittings must be in place and
fastened correctly.
•
The front side plate screw should not be tightened.
•
The MSD is connected to a grounded power source.
•
The GC/MSD interface extends into the GC oven.
•
A conditioned capillary column is installed in the GC
inlet and in the GC/MSD interface.
•
The GC is on, but the heated zones for the GC/MSD
interface, the GC inlet, and the oven are off.
•
Carrier gas of at least 99.9995% purity is plumbed to the
GC with the recommended traps.
•
The foreline pump exhaust is properly vented.
Open the MSD analyzer top cover.
9
Close the MSD vent valve.
10
Press the Power button on the front of the MSD to power it
11
on. The foreline pump will make a gurgling noise.
