Editing a Sequence
To delete an entry from the sequence, select the entry in the list and
press the Del button. To change the tube range, you must add a new
entry with the revised tube range and then delete the old entry.
If you edit the methods called by your sequence, the sequence will
use the revised methods. If you need to edit a method but do not
want to affect your sequence, then save the revised method with a
different name.
Status Tab
The status tab consists of four views: Temperature, Timing,
Options and PNU. You select the desired view by selecting the
corresponding radio button on the lower half of the touch screen.
You can view the Actual values as they are on the ATD/TD or you
can view the Set Points. If you are viewing the Actual values, the
parameters that have reached their set point are displayed in black,
those that are still changing are highlighted in yellow and displayed
in red.
Normally you will use the Status display to monitor the instrument.
You can also use the Status tab to create a method. By using the
Status tab, rather than the Method Editor, you can enter
parameters, run an analysis, change the settings based on the results
and then perform another analysis. You can proceed in this manner
until you have obtained the desired method parameters. Once the
method is complete you can save it using, Save As from the Tools
menu, and use it on the Run tab. Refer to Chapter 5 for details on
creating a method.
Temperature Tab
There are five temperature settings for the TD. The Tube oven
temperature, the heated Valve, the Transfer line temperature and
the cold trap secondary desorption temperatures (Low, High). You
will also set the heating Rate for secondary trap desorption.
Entering a value of zero for any temperature parameter, disables the
related heater. For example, if you enter zero for the transfer line
