B.6 ACQUITY column manager with active preheating and
auxiliary column manager specifications
ABPR sensor Measures system pressure before the ABPR operation
ensuring that the pressure does not exceed pressure
performance specifications.
ABPR dynamic regulating valve Adjusts the system pressure to compensate for thermal
changes and solvent-composition changes when delivering
pressure gradients.
ABPR static regulating valve. Maintains the dynamic valve pressure to that above the
critical pressure of CO
2
.
ABPR heating system Maintains the temperature of the static regulator at a set
elevated temperature range during the CO
2
liquid-to-gas
phase transition to prevent the co-solvents from freezing.
ABPR heater:
Temperature stability: +/− 2.0°C
ABPR operating pressures Minimum: 1500 psi
Maximum: 6000 psi
ABPR flow rate operating range Minimum: 0.5 mL/min
Maximum flow rate: 4.0 mL/min
Leak management Drip trays manage all leaks from the ccManager into a drain
tube at the front of the module and empty the liquid into a
user-supplied waste container.

Feature Specification
Column 2.1 to 4.6 mm I.D. up to 150 mm in length
With guard column or filter 30 mm length max.
Columns capacity CM-A: Two columns, as standard (maximum length of 150
mm with filter or guard column) or four columns (maximum
length of 50 mm) with the optional tubing kit, up to 4.6 mm
ID.
CM-AUX: Two columns (maximum length of 150 mm, with
filter or guard column). As many as two CM-AUX units can
be configured with one CM-A to support as many as six
columns.
Switching valves Two injector style, nine-port, eight-position valves (CM-A
only); provides programmable automatic, random-access
switching; waste and bypass positions for rapid solvent
changeover.
