Working with Sequences (Sequences and Sequence Templates)
Working with Sequences (Sequences and Sequence Templates) 
Sequences (Sequences and Sequence Templates) are accessed and created 
from the Sequence menu. Sequences may be created and saved in the same 
way as methods. When you save a sequence, a file is created with a .S 
extension. When you want to edit or use the sequence again, you access it by, 
for example, using the Load Sequence item in the Sequence menu.
Priority Samples 
A currently running sequence can be paused after the current method is 
completed. The sequence can be paused to allow the analysis of a priority 
sample by the same or another method. The sequence can then be resumed, 
where the sequence continues with the sample at which the sequence was 
paused.
Sequencing with Control Samples
Control samples can be specified in the Sample Type field of the sequence 
table. The method used to analyze the control sample must contain a 
calibration table where control sample limits for one of the compounds are 
specified. If the control sample limits you specified are exceeded, the sequence 
is stopped and a message is written into the logbook. If you are using one of 
the ChemStation report styles, the control sample limits are also printed on 
the reports generated for these analyses. For more information on how to 
define a sequence with control samples, see the How To section of the online 
help system.
Stopping a Sequence 
The currently active run will be completed before the sequence stops. A 
stopped sequence can never be resumed.
