General Outline of the Procedure
Page 72
1. Measure the backpressure of the waste line (see
Backpressure of the Waste Line
Flow path: Pump – waste line
2. Measure the backpressure of the Vanquish system including the
column, detector inlet capillary and waste line (without installed
flow cell and additional module) (see
System Backpressure (Without Flow Cell and Additional Module)
(} page 74)).
Flow path: Pump – autosampler – column – waste line
3. Determine the backpressure at the flow cell outlet caused by the
connected additional module (see
the Flow Cell Outlet Caused by the Connected Additional Module
(Without Flow Cell)
Flow path: Pump – autosampler – column – additional module (-
waste line)
4. Determine the backpressure of the flow cell (see
Backpressure of the Flow Cell
Flow path: Pump – autosampler – column – flow cell – waste line
5. Calculate the pressure at the inlet port of the flow cell (see
Calculating the Pressure at the Inlet Port of the Flow Cell
(} page 79)).
Flow path: Pump – autosampler – column – flow cell – additional
module (- waste line)
WARNING—Escape of Hazardous Substances from Flow Connections
Flow and capillary connections can be filled with substances that can
pose health risks. Solvent can spray when capillaries burst, slip out of
their fittings, or are not properly tightened or when capillary
connections are otherwise open.
• Wear appropriate protective equipment and follow good laboratory
practice.
• Before starting maintenance or repair procedures, flush out harmful
substances with an appropriate solvent.
