hplc Column Selection
for 4 or 6 columns
Up to 6 HPLC columns can be
rapidly accessed by column
selection valves, eliminating the
instrument downtime involved
in exchanging columns and the
leakage due to repeated changing
of tubing fittings. The columns
are installed as a part of the loop
system, as shown in this drawing.
A 6 position valve can support
6 columns.
hplc column selection for up to
10 columns
This example illustrates an SD
(UW type) selector used for HPLC
column selection. This allows
multiple columns to be installed
permanently in the system,
eliminating instrument downtime
and leakage potential resulting
from having to change columns
repeatedly. The SDUW valve selects
only column inlets – the column
outlets are connected to the
detector via a low-volume manifold.
The manifold is sold separately.
