Using the Module
Configuration and Operation of the Fraction Collector
Delay Evaluation
The Delay Evaluation window enables you to determine the delay times/volumes
between the peak detector(s) and the fraction collector. The Delay Evaluation
window is split into two sections:
• the left pane contains the delay calculations
• the right pane shows the signals from the peak detector(s) and the fraction
collector delay sensor.
Delay Calibration
The Delay Calibration pane contains the parameters and results of the delay
calculations:
Load Data File Displays a file selection dialog box that allows you to select a
delay calibration data file to use for the calculation of the delay
times/volumes.
Pump Flow The pump flow as given in the data file or as a user-specified
value. The flow specified here is used to calculate the delay
volumes.
Click Change Flow to display the Change Pump Flow dialog box,
which allows you to change the pump flow that is used for the
delay calculations.
Delay Volumes The delay volumes are shown in a four-column table:
Peak Detector
The type ID and serial number of the peak detector.
Calibration Signal
Click the down-arrow and select the signal to use for the delay
calibration for this peak detector from the drop-down list.
Calc. Delay Time (min)
The calculated delay time (the difference between the retention
time of the target peak given by the fraction collector delay
sensor and the retention time of the peak in the selected
calibration signal).
Delay Volume (mL)
The calculated delay volume (the product of the delay time and
the specified flow).
