Note
Do not move the measuring cell for at least 5 seconds after having
inserted it.
During this time, data is read from the chip of the measuring cell
and written into the database. This process must not be interrup-
ted, because otherwise the data may be transferred incorrectly or
incompletely.
3 Test at low flow
￭ In the program part Manual of MagIC Net™, set the flow of the
high pressure pump to 0.2 mL/min and start the high pressure
pump.
￭ Watch the detector output capillary: Liquid must emerge from the
end of the detector output capillary.
If no liquid emerges from the end of the detector output capillary:
– Undo the capillary from the Out connection on the meas-
uring cell and check whether the end has been squeezed by
the pressure screw.
– Shorten the capillary and fasten once again to the Out con-
nector on the measuring cell.
