Performing a column compensation run
All conditions must be identical in the column compensation run and the real run. The same
detector and column must be used, operating under the same temperature and gas flow
conditions.
Up to four column compensation runs can be made. The GC retains the results of these runs
for later use.
Any column compensation run can then be used to compensate a rising baseline during a run.
1 With the Tools page displayed, as shown in Figure 54, select the desired
Column Compensation in the Start Specified Run column. The GC performs the column
compensation run. No injection occurs as a part of this run.
2 Use the connected data system to edit the method. Set the detector to Subtract from
Signal: Column compensation Curve #x (where x is the number of the column
compensation run).
3 Run the method. The results use the column compensation run data to compensate for
baseline changes in the column.
