Delay volumes for extended
systems
If modules and tubing are added to, or subtracted from, the ÄKTA avant system between
the UV monitor and the fraction collector, use the standard delay volumes values in
Standard delay volumes in ÄKTA avant 25 and ÄKTA avant 150, on page 507 and correct
with tubing volumes from Section 9.3 Tubing and connectors, on page 432 and component
volumes from Section 9.13 Component volumes, on page 509 to calculate a new delay
volume. Add this delay volume in UNICORN.
For pH-valve V9-pH and V9H-pH always use the volume for the valve in by-
pass position. The system automatically adds the volumes for the flow restrictor
and the pH flow cell when if they are part of the system.
