I am faced with a bit of a puzzle I hope someone can help with.

I am using a 6890GC with EZChrom CDS to run 2 methods. Both methods are operated in split mode with a split flow of 192 mL/min, the column configured in each method is the same and both methods are operated in constant pressure mode with a nominal flow of 2.4 mL/min.

The Total Flow on one method is 197.1 mL/min but it is 196.6 mL/min on the 2nd method.

Why is there a difference in the Total Flow between the 2 methods?
