To set the MSD analyzer temperatures
Setpoints for the MSD ion source and mass filter (quad) temperatures are stored
in the current tune (*.u) file. When a method is loaded, the setpoints in the tune
file associated with that method are downloaded automatically.
Software changes
The software is revised periodically. If the steps in this procedure do not match
your MSD ChemStation software, refer to the manuals and online help supplied
with the software for more information.
1 In Instrument Control view, select
Edit MS Tune Parameters from the
Instrument menu.
2 Select the tune file you plan to use with your method from the Load MS
Tune File dialog box.
3 Select
Temperatures from the MoreParams menu.
4 Type the desired Source and Quad (mass filter) temperatures in the
setpoint fields and click
OK.
Recommended settings for operation are:
Source: 230°C
Quad: 150°C
The GC/MSD interface, ion source, and quadrupole heated zones interact. The
analyzer heaters may not be able to accurately control temperatures if the setpoint
for one zone is much lower than that of an adjacent zone.
5 Click
OK in the Edit Parameters window to apply the new temperature
setpoints.
6 When the
Save MS Tune File dialog box appears, either click OK to save your
changes to the same file or type a new file name and click
OK.
&$87,21
Do not exceed 200°C for the quadrupole or 250°C for the source.
