7. Press the green Start button to run the sequence.
The instrument will configure itself based on the first
method. Once the instrument has reached the set points,
the first tube will be loaded and the analyses will
continue as determined by the method.
Shutdown
Normally you do not need to shut down the instrument. You can put
the instrument into economy mode overnight and over the weekend.
See Preferences Tab on page 117. If the instrument will not be used
for more than two days, you may opt to shut it down.
If the instrument is to be disconnected with a septum from the GC be
sure to cap the end of the fused silica transfer line to prevent
contamination of the system.
To shut down the ATD or TD:
1. Stop the running method by pressing the Stop button.
2. Wait until the sample tube has been unloaded to the
carousel or unload the tube from the TD.
3. Switch off the power to the ATD/TD.
4. Open the GC oven door to cool down the column before
removing the carrier gas through it.
5. Turn off the carrier gas supply.
6. Switch off any external accessories.
CAUTION
Before attempting to disconnect the TD/ATD from the GC,
read and strictly follow the next set of instructions to protect
the GC column and specific detectors.
The TD/ATD is the sole supplier of carrier gas to the GC!
a) Ensure that both the GC oven/detectors are cool.
b) If an MS is used, the GC-MS transfer line (if used) and the
Ion Source are cool. Filament is OFF.
c) All TD/ATD zones (trap, heated valve, transfer line) are
cool.
