alarm is enabled, the run is paused.
Note:
Check if the air trap has run out of liquid.
Make sure that the the air trap is filled before setting it in-line. The recommen-
dation is to always have some liquid in the air trap because in-line position is
default. For information on how to fill the air trap, see the ÄKTA pilot 600
Operating Instructions.
Note:
When to use
Some examples when to use the air trap are shown below.
•
to trap degassed bubbles released from cold solutions
•
to catch any air introduced to the flow path during sample loading, for example
when applying all sample using an external air sensor
At flow rates > 100 mL/min the air trap can always be in-line.
