has been selected, then you only need to enter the tube
range. The selected method will be displayed and you
will not be able to access the drop down method list.
2. Beside the Tubes label radio button, you will enter the
start and stop tubes. The tube range will default to 1 to
50. Press the first entry box to enable the option. If you
are using a TD, the tube range is fixed at 1.
3. Press the plus or minus button to select the desired start
tube. Then enter the desired end tube.
4. From the method drop-down box, select the method to
be used for the selected range of tubes.
5. The Start button will be green, indicating that ATD/TD
and the GC are ready. Press the Start button to begin the
analysis.
The ATD/TD will configure itself based on the method parameters
currently displayed on the Status tab. The instrument status displays
“Equalizing” until the instrument reaches all of the set points. Once
it has reached the set points, a tube will be loaded and the analyses
will continue as determined by the method.
Creating a Sequence
On the ATD, you can use a sequence of methods to analyze a series
of tubes.
NOTE: When setting up a sequence that contains many methods,
there is a considerable delay before the sequence sets-up.
On the TD, you can run a series of methods on a single tube. You
will not be able to run a sequence of methods on a series of tubes, as
the tube range is fixed at 1. You must have Multiple Method
Operation enabled on the Preferences/Run tab see Figure 28.
The options on the Run tab allow you to select a range of tubes and
then specify a method to analyze the samples. You then select the
next range of tubes and select another method. You can also analyze
the same range of tubes using different methods.
You will not be able to edit any of the selected methods if method
editing has been disabled from the Preferences/Run tab. See
Preferences/Run tab section later in this chapter.
