The air sensors are inserted into ports on the air sensor module. ChromLab detects
the presence or absence of air sensors in the air sensor module. If you have fewer
than four air sensors in the module, you must cover the unoccupied ports with a
protective blank cover that Bio-Rad provides to prevent liquid from entering into the
module’s electronic circuitry.
The air sensors can be connected to
 The inlet port on the sample pump
 The inlet port on system pump A
 The inlet port on system pump B
 Any position along the flow path of the instrument, for example
 Sample inject valve
 Buffer inlet valve
