Collect Using a Delay Function
User Guide | 69
To run a Collect method using a delay function
1. On the Main screen, set the fraction size units (min, ml, or drops).
2. From the Advanced Collection screen, press Collect (F4).
If collecting by volume, the delay volume can be entered directly. If collecting by
time, the delay time is calculated from the delay volume divided by the flow
rate.
3. To calculate the delay in drops, divide the delay volume by the drop volume
(1 drop = 50 µl for the standard drophead or = 25 µl for the microplate
drophead).
The examples on the following pages demonstrate the use of the delay function.
