Fraction Collector Principle

Fraction Collector Principle
The movements of the Fraction Collector components during the sequence are
monitored continuously by the Fraction Collector processor. The processor
defines specific time windows and mechanical ranges for each movement. If a
specific step of the sequence is not completed successfully, an error message is
generated.
The standard fractioning sequence occurs in the following order:
1 The Fraction Collector starts always from the home position.
2 When the sample is injected, the fraction probe with diverter valve moves to
3 When the trigger is given by the detector, the diverter valve opens to collect
4 When the trigger is given by the detector, the diverter valve closes and the
Fractioning Sequence
Before the start of the sequence, and during an analysis, the diverter valve is
in the fraction start position. In this position, the mobile phase flows through
the diverter valve towards waste.
