How many detectors have you in your system?. If you have two detectors, you must check what detector are you using for column compensation (in "Options check box"). Normally, default is detector1 for column 1 and detector2 for column2. If this is so, you must check that electrometer is "on" in both of them. (Please, excuse me my awful English).
