manager base unit and two CM-AUX modules can accommodate as many as six long columns
(two columns in the base unit).
1.3.4.1 Active solvent conditioning
HPLC and UPLC applications benefit from pre-column, mobile-phase heating to improve
chromatographic separations. The column heaters in the system use an active preheater to
condition solvent as it enters the column. The preheater raises the temperature of the incoming
mobile phase (and injected sample) to the same set point as that of the column compartment.
Tip:
Active preheating is the default configuration for the system. When using the CH-A, an
optional, passive, column stabilizer is available for existing chromatographic methods not suitable
for active preheating.
1.3.5 Column Module Switch Box (optional)
With the optional Waters Column Module Switch Box, you can physically connect a column
heater (CH-A) and a 30-cm column module (either a CH-30A or a 30-cm CHC) to the sample
manager - flow-through-needle (SM-FTN) and switch the electrical control of the column modules
via the SM-FTN console.
The switch box is mounted to the rear of the SM-FTN. The SM-FTN interconnect cable is
connected to the sample manager (SM) port of the switch box, the CH-A interconnect cable is
connected to the CH-A port, and either the CH-30A or the 30-cm CHC interconnect cable is
connected to the 30-cm port.

1.3.6 Sample organizer (optional)
Requirement:
Verify that the sample organizer you use with your system is compatible with
sample managers that have a rotary tray.
The sample organizer stores multiple microtiter or vial plates and transfers them to and from the
sample manager. This automates processing and increases throughput.
The sample organizer’s storage shelf compartment can hold a selection of ANSI plates, which
you load into the organizer through a large, swing-open front door. Heaters and coolers thermally
condition the shelf compartment and together with the sample manager’s heater/cooler, maintain
the temperature at a set point determined by the user.
