Flow Connections to the Flow Cell

Page 66
Connect the inlet capillary and waste line to the flow cell when the flow
cell is installed to the device.
NOTICE
Flow cells are highly sensitive to contamination, clogging and high
backpressures. Even if the pressure exceeds the upper limit for a very
short time only, the flow cell may be permanently damaged. Observe
the following notes when connecting the flow cell to the system flow
path:
• Backpressures that exceed the specified maximum pressure limit of
the flow cell can destroy the flow cell. Never expose the flow cell to
excessive backpressure. When connecting a component in the flow
path after the flow cell, observe the specified backpressure for the
flow cell.
• Avoid clogging of the flow cell or waste line.
• Improperly set up flow connections can lead to leaks on the flow cell
or even destroy the flow cell.
• Use only clean Viper capillaries which were provided for the flow cell
and which have been properly protected by their cap before.
• Use only the waste line which was provided for the flow cell.
• Use the flow cell only with a column or a filter frit connected in the
flow path before the flow cell.
• Do not invert the flow cell inlet and outlet for normal flow cell
operation. Inverting the flow connections is only allowed for the
back-flushing procedure that is described in the manual.
• Use only the waste line connection that is provided for your
detector.
• Connect the waste line to the flow cell only as described in the
manual.
• Do not discharge waste from the flow cell through the open leakage
drain system of the Vanquish system.
In addition, observe the guidelines for proper connection of the flow cell
in General Information and Guidelines (} page 59).
