Column Configuration for the 8860/8890 GC System

This Information Applies To: 8860/8890 GC, Smart Key

Issue

f the column configuration has been defined in the method, the instrument will calculate the pressure to maintain the target column flow rate. The column configuration must be edited or calibrated when a new column is installed, or the column is trimmed during routine maintenance.

Steps to follow

The column configuration can be edited by the following methods:

• Touch screen interface

• Browser interface by editing the configuration settings

• Browser interface by calibrating the column

• OpenLab CDS version 2.x, see GC Column Configuration Using OpenLab CDS Software.

  Tip: The 8890 GC is Smart Key compatible. The Smart Key compatible columns are supplied with a Smart Key that plugs into the instrument, and automatically identifies the column and monitors column use. Column length can be adjusted through the calibration options in the browser interface or the OpenLab CDS version 2x software. Calibration changes are saved on the Smart Key and, thus, adapted parameters will be available when the column and Smart Key are moved to another GC.
