This Information Applies To: 2100 Bioanalyzer system, 2100 Expert software Issue: How to identify and troubleshoot late migration of the ladder, marker, and sample peaks in data generated on the Agilent 2100 Bioanalyzer system. Background The ladder, marker, and sample peaks in the affected run take considerably longer to migrate compared to the peaks in the demo file of the same assay type. Late migration is usually accompanied by errors, similar to the ones shown in Figure 1 . These...

This Information Applies To: Agilent 8890/8860 GC Systems Issue Early Maintenance Feedback is a useful feature on Agilent GC Systems and software that allows a user to monitor the maintenance needed on their GC. This feature allows for users to get a reminder that maintenance is due on their instrument before it causes a chromatography or even a hardware issue. If you are changing parts on your GC on a scheduled basis, either based on a certain passing of time or a specific number of injections...
