Air Sensors Tab
The system supports up to two air sensor modules and up to eight air sensors. Each
air sensor module can contain up to four air sensors. The system detects the
number of air sensors that are attached to the instrument.
Air sensors can be set to detect air, indicating end of buffer, in lines connected to
the system pumps. When the air sensor detects end of buffer, the system stops the
system pumps and the run. You can continue the run after replenishing the buffer
and purging the lines.
Air sensors can also be set to detect air, indicating end of sample, in lines
connected to the sample pump. When the sample pump is used to load sample in
manual mode and the air sensor detects end of sample, the system stops the
sample pump to keep it from pumping air onto the column. When the air sensor
detects end of sample during the sample application phase, the sample pump
stops. In this case the run proceeds to the next phase.
To activate air sensors
1. Select File > System Settings to open the System Settings dialog box.
2. Choose the Air Sensors tab.
By default, only the air sensors that the system detects are enabled. The other
sensors are disabled.
