5.4 Flow Schematic
The figure below shows the Parallel LC setup. With this configuration, two Chromeleon
instruments (“time bases”) share the column compartment and the autosampler. The
autosampler is alternated between two parallel flow paths to allow for synchronized analyses
on two individual columns. Two detectors independently and simultaneously acquire the
related signals.
Note:
The eluents in both systems have to be fully miscible; both columns
have to be operated at the same column temperature as they are located
in the same column compartment; the initial eluent compositions on
both columns should be comparable to support fast flow path switching;
comparable cycle times for both methods are advantageous.
To ease the installation of the capillaries, it is helpful to establish all
connections at the TCC 6-port valve left first, and to position both
towers at the recommended distance (
5.3) for connecting the pumps
and the autosampler afterwards.
Columns with a length of 200 mm or more are optimally positioned at
the lower end of the TCC.
