External air sensors

Introduction
Two external air sensors are available as options. The difference is their size and where
they can be installed. ÄKTA avant supports installation of one external air sensor at a
time.
L9-1.5 external air sensor
L9-1.5 has a inner diameter (i.d.) of 1.5 mm and is designed for 1.6 mm i.d. tubing at the
low pressure side before the pumps. It is installed before the Sample inlet valve and is
used to prevent air from entering the Sample inlet valve.
L9-1.2 external air sensor
L9-1.2 has a 1.2 mm i.d. and is designed for 1/16" tubing outer diameter at the high
pressure side before the column. It is installed after the Injection valve and is used to
prevent air from entering the Column valve.
The air sensors can be attached to the instrument using the rails. No module panels
need to be removed.
The Run Data for air sensors shows the status of the air sensor. If an alarm is triggered
and then acknowledged, the Run Data will be reset to No Air even if there still is air in
the sensor. When the flow starts another alarm will go off if air is still present.
