DescriptionInstruction name
Sensitivity external air sensor X is used together with the Alarm
external air sensor X instruction and sets the sensitivity of the
optional air sensor number X. The optional air sensor can be locat-
ed either before any of the inlets A or B or after the injection valve.
Sensitivity external air sensor X
Normal (30 µl) is used to detect when a buffer or sample vessel
is empty. High (10 µl) is used to detect small air bubbles
- When located before an inlet, the default sensitivity is Normal.
- When located after the injection valve, the default sensitivity is
High and the pump currently pumping onto the column is used
for calculating the air volume for the external air sensor.
Note:
Using an air sensor after the injection valve is only useful when
running at lower pressures. High pressure dissolves any small air
bubbles present.
