Triggering of 2D-LC
Concept of Peak Triggering
Peak-triggered LC-LC
One or more peaks of the first dimension exceeding a given level are injected
onto the
2
D column. Further peaks eluted from the
1
D column during the second
dimension gradient time are ignored.

Concept of Peak Triggering
Triggering is done in advanced settings similar to integrator settings by threshold
and/or slope, see “Use Peak Trigger” on page 148.
