Stoptime (Modular LC Fraction Collector Cluster)

Stoptime enables you to set a time at which the fraction collector or fraction collector cluster stops an analysis.

Limits: 0.01 to 99999.00 minutes or As Pump/Injector (the Stoptime of the pump or injector when an Agilent pump or injector is configured).

When a Stoptime is set for a module and that time is reached during the run, the module stops its run, that is, it stops data acquisition and starts counting the Posttime.

The Stoptime of the whole system is determined as follows:

• If your system contains an Agilent pump, Agilent valve drive G1170A or Agilent sampler, the Stoptime of the system is determined by the shortest Stoptime set for any of these modules.

• If your system does not contain any of these modules, the Stoptime is determined by the shortest Stoptime set for any of the remaining Agilent modules in the system.

The Stoptime behavior is determined by the firmware revision of the Fraction Collector: If the firmware revision of the fraction collector is earlier than A.06.54 and the fraction collector is used with other Agilent Modular LC modules, the fraction collector stoptime also stops the other modules. If the firmware revision of the fraction collector is A.06.54 or later and the fraction collector is used with other Agilent Modular LC modules, the fraction collector stoptime stops the fraction collector only and does not stop any other modules.

If one of the fraction collectors in the cluster has firmware revision earlier than A.06.54, the fraction collector cluster acts as stoptime master.
