Trigger Combinations

Use the Trigger Combinations to specify how multiple peak triggers are combined to start or stop Fraction Collection. The graphic above the option shows the collection period.

The following modes are available:

AND Collection of a fraction is started when all peak detectors have sent a start trigger, and continues until one detector sends a stop trigger.
OR Collection of a fraction is started when at least one peak detector has sent a start trigger, and continues until all detectors send a stop trigger.
AND/OR Collection of a fraction is started when all peak detectors have sent a start trigger, and continues until all detectors send a stop trigger (AND condition for start, OR condition for stop).
Conjunction Collection of a fraction is started when all peak detectors have sent a start trigger, and continues until one detector sends a stop trigger (OR condition for signals within one detector, AND condition for different detectors).
