4 Installing 7890 GC Columns
To Calibrate Column Flow Linear Velocity in a 7890 GC
96 5977B Series MSD Operating Manual
10 Verify that the parameters listed (temperature, inlet and outlet pressures, and
gas type) are those used in the method to determine the holdup time.
Change any parameters that are different than those used in your method.
11 Enter the recorded retention time in the Holdup Time field. Move the cursor to
another parameter’s field and the calibrated column length appears.
12 Click OK to save the changes and exit the dialog.
13 Click OK on the Calibrate Columns dialog to save the calibration.
With capillary columns, such as those used with the MSD, linear velocity is often
measured rather than volumetric flow rate.
