Pressure alarms

Introduction
The ÄKTA go instrument is equipped with a pressure monitor directly after the pump,
which measures the highest pressure in the instrument. The advanced column valve,
V9-C, adds two extra pressure sensors, one directly before the column and one directly
after the column. These pressure monitors enable the measurement of pre-column
pressure, which is the pressure on the column hardware, and delta-column pressure,
which is the pressure on the packed bed.
Methods automatically include a pressure alarm based on the specifications of the
chosen column. When performing a manual run, you must set the pressure limits yourself.
Note:
