Auxiliary column manager
In addition to the column manager, the system can include one or two
auxiliary column manager modules. The column manager acts as a master to
the optional auxiliary column manager modules. Although the auxiliary
column manager modules have their own power supply, the column manager
controls their power state.
Auxiliary column manager modules are not fitted with switching valves. All
plumbing connections are made to the switching valves in the column
manager.
The auxiliary column manager can accommodate two 100- or 150-mm columns
with inside diameters of up to 4.6 mm.
Each auxiliary column manager module consists of two independently heated
and cooled column troughs. Like the column manager, the temperature range
of the auxiliary column manager module is 4 to 90 °C. Each trough can
accommodate one column of 50 to 150-mm, and an active preheater.
Description
Contains the column, column heater, in-line filter, and
active preheater assemblies. The column compartment
insulates the column from changes in ambient
temperature.
Protects the analytical column against contamination by
trapping impurities before they reach the column.
Heats the incoming solvent to the specified column
temperature prior to entry to the column.
Secures the active preheater in the column
compartment.
The inlet and outlet column switching-valves allow for
programmable switching access to any column installed
in the column manager as well as to column bypass
mode and to waste.
Captures any leakage from the column or column
connections and routes it into the drip management
system.
