• If using multi-detector configurations, configurations that include a
diverter valve, and hyphenated techniques like LC-MS or
fractionation after a LightPipe flow cell, install an overpressure relief
valve. The valve is intended to limit pressure in an error case. It is
not intended to limit overpressure events as a consequence of the
system configuration and/or instrument method not observing the
flow cell pressure limit. Repetitive triggers due to such instrument
methods limit the ability of the valve to function correctly and
reduce the lifetime of the flow cell.
To protect the flow cell against overpressure and pressure shocks,
observe the following:
- Set up instrument methods that ensure that the pressure inside
the flow cell stays well within its pressure specification (for
information on how to determine the pressure inside the flow cell of
a configuration, see the Determining the Pressure inside the Flow
Cell section in this manual).
- Observe the pressure limit at all times.
- If the valve has opened, find, and resolve the root cause for
opening and ensure that the valve is tight before restarting
measurements.
- If using mass spectrometers with diverter valves that offer a Make-
Before-Break connection, use this capability.
To set up the flow connections and complete the installation of the
device, follow these steps:
1. Set up the flow connections to the flow cell (see
to the Flow Cell (} page 66)).
2. Connect the device to the drain system (refer to the Vanquish
System Operating Manual).
For installation instructions, guidelines, and handling recommendations,
see Connecting Fittings, Capillaries, and Tubing
Flow connections between the modules of the Vanquish system are
guided through either the tubing chase in the devices or the guide holes
or capillary clips of the devices.
To guide certain tubes and lines from the top module to the bottom
module in the Vanquish system stack, the stackable modules have a
tubing chase on the inside right. The tubing chase provides four tubing
guides.
