5. Connect the in-line filter to the system flow path in a post-column
position. Observe the direction of flow as indicated on the filter.
a) Connect the capillary from the column outlet to the upstream
end of the in-line filter and route it to the waste reservoir.
b) Flush the in-line filter with mobile phase at a flow rate of about
5 mL/min.
c) Connect the downstream end of the in-line filter as required by
the system flow path (see next section).
Depending on the modules in your HPLC system, you can connect the
inlet capillary to the detector as follows:
• Directly from the column
–or–
•
From the flow cell of a first detector, such as a diode array detector,
in the HPLC system flow path (series flow connection)
In a series liquid flow configuration, one flow path from the pump is
used for both detectors installed in the system.
TIP Alternatively, you can connect the detector from a flow-splitting
device (parallel flow connection). In a parallel liquid flow configuration,
one flow path from the pump is split for two detecting devices. For
further information on series and parallel liquid flow configurations, see
section 5.6.5.3, page 94.
From the detector ship kit:
• RheFlex fittings

Inlet capillary, PEEK, 0.005" x 1/16" (I.D. x O.D.), red
TIP Keep the capillary connection to the charged aerosol detector as
short as possible to minimize peak dispersion.
