The four options for unpacking are used to simplify unpacking of columns. Before using
an unpacking option, make sure to read each column instruction.
Column pressure monitoring
The pre- and post-column pressure sensors are located at the inlet and outlet of the
column valve.
The pressure drop between a sensor and a column is automatically compensated. This
affects pressures at higher flow rates (>600 mL/min).
There are four pressure signals, see the image and table below.
