Operating Manual
Interrupted Operation
• During short analysis breaks, take appropriate measures to protect
the flow cell
:
¨
Never leave any substances in the flow cell without flow. Avoid
leaving particularly any aggressive solvents in the flow cell for a
longer time.
¨
Without flow, air bubbles in the flow cell can accelerate the
deposition of substances. Never leave air bubbles in the flow cell
without flow.
¨
If one or both lamps are turned on, operate the detector with a
low flow rate to protect the flow cell from the light and to
prevent the growth of algae.
¨
Additionally, follow the guidelines in Short-Term Shutdown
(Interruption of Operation) ( } page 108) .
• During long analysis breaks, take appropriate measures to protect
the flow cell
:
¨
Turn off the lamps to protect the flow cell from the light.
Otherwise, the radiation from the lamps may damage the flow
cell.
¨
If the pump flow is stopped for a longer time, fill the flow cell
with a high-purity solvent, for example, isopropanol.
¨ Additionally, follow the guidelines in Long-Term Shutdown
(

Shipment
When shipping the instrument, remove the flow cell and install the flow
cell cover to protect the flow cell opening. The flow cell must be shipped
in its original packaging.
• To remove the flow cell, see Removing the Flow Cell ( } page 134) .
• To install the cover, see the instructions at the end of Installing a
Flow Cell ( } page 62) .
