Part 6. Calibrating your capillary column (optional) Columns and Traps
Column calibration procedures
8. The GC displays the current calibration mode for the column. In this exam-
ple, the column is uncalibrated.
9. To recalibrate or change calibration mode, press [Mode/Type] to see the
column calibration mode menu.
10. Scroll to Length or Diameter and press [Enter]. The following menu
appears:
11. Scroll to Measured flow and enter the corrected column flow rate (in
mL⁄min) from the run performed above.
12. Scroll to Unretain pk and enter the actual elution time from the run
performed above.
13. When you press [Enter], the GC will estimate the column length or diameter
based on the elution time input and will now use that data for all calculations.
The * indicates the current mode
