1 Overview
The ACQUITY Arc 30-cm Column Heater (30-cm CH) and 30-cm Column Heater/Cooler (30-cm
CHC) are the standard column heating and column heating/cooling modules that manage and
maintain column temperature for ACQUITY Arc systems. Except for the 30-cm CHC module's
cooling capability and the additional components required to support this capability, the modules
are identical. The base configuration of both modules includes a passive preheater that helps
achieve the column's set-point temperature within the column compartment. Both modules
support the column-switching valve kit option that provides automated column switching to
method conditions. 30-cm CH and 30-cm CHC modules in Bio systems are equipped with bio-
compatible inlet tubing, outlet tubing, and preheaters.
Restriction: You cannot use the 30-cm CH or 30-cm CHC module's passive preheater in
concert with the optional column-selection valve.
Restriction: You cannot use the 30-cm CH or 30-cm CHC module in conjunction with the
optional 30-cm column heater with active preheater module (CH-30A).
The 30-cm CH and 30-cm CHC column compartment accommodates LC columns with
dimensions as large as 7.8-mm internal diameter (ID) and 30-cm long. For additional information
about supported columns, see "Column configurations".
To reduce dispersion associated with extra column volume and minimize the length of tubing
between system instruments, the 30-cm CH or 30-cm CHC module is mounted next to the
ACQUITY Arc system stack, as shown in the following figure.
