System settings
The sensitivity of the air sensor can be set.
Usage Air volume detected Parameter
ÄKTA pure 150 ÄKTA pure 25
Detect empty
buffer/sample vessels 100 μl 30 μl Normal (default)
Detect even small air
bubbles 30 μl 10 μl High
The sensitivity should be set to Normal when the air sensor is located before the System pump
(Air sensor ext - Before pump A or Air sensor ext - Before pump B). Due to higher pressure
and risk of small air bubbles, the sensitivity should be set to High when the air sensor is located
after the Injection valve (Air sensor ext - after Injection valve).
