 Auto BTU Start Up and Valve Timing

The Auto BTU Start Up process, which takes 

about an hour to complete, automatically 

performs the following sequence of tasks: 

1. Sets the timing for each valve.
2. Matches all the component peaks.
3. Adjusts the timed events based on peak 

integration times.

4. Runs a calibration.
5. Checks the range and order of response 

factors.

6. Adjusts the retention time deviations to 

avoid peak overlapping.

You can also initiate a valve timing run, which 

is the first step of the  Auto BTU Start Up 

process, independently of that process.  See 

more information.

To launch the Auto BTU Start Up process, do 

the following:

1. If the GC is currently performing an 

analysis, select Halt from the Control menu 

to put the GC in Idle mode after the current 

analysis run.
