Module Description
ACQUITY UPC2
Convergence manager
(ccManager)
Regulates and monitors the incoming flow and pressure of liquid CO2
in the system through these mechanisms:
• Electronically controlled CO2inlet shutoff valve
• Overpressure protection
• Auxiliary valve for venting the injection loop
• Automated back pressure regulator (ABPR)
ACQUITY UPC2
Sample manager - fixed
loop
(SM-FL)
Controls sample injections using a fixed-loop injector. It also monitors
and regulates the depressurization of CO2in the flow path during an
injection sequence.
Column manager (CM-A)
and auxiliary column
manager (CM-AUX)
Regulates the column temperature to between 4 and 90 ºC. The
temperature of each column trough can be independently set in
0.1 ºC increments. A supplementary pre-heating device (active
preheater) can also be installed, to heat the incoming solvent before
it enters the column. The CM-A can accommodate two 100- or
150-mm columns with inside diameters of up to 4.6 mm.
The system can include as many as two CM-AUX modules. The
CM-AUX modules can each accommodate as many as two columns
ranging in size from 50- to 150-mm lengths with internal dimensions
from 2.1 to 4.6 mm.
Additionally, the CM-Aux module includes two independently heated
or cooled column troughs, for inlet configuration on the left-hand or
right-hand side. Each column position includes an active pre-heater
for both configurations, to ensure specified thermodynamic
conditions of the column over the range of allowable ambient
conditions.
ACQUITY 30-cm
single-zone column
manager
(CM-30S)
One CM-30S provides support for as many as eight columns in a
single temperature zone. Under Empower software control, two
CM-30S provide support for as many as 15 columns in two heated
temperature zones (5 ºC above ambient to 90 ºC). Columns range in
size from 2.1 to 8.0-mm (internal diameter) and 30 mm to 300 mm
long.
ACQUITY UPC2
Binary solvent manager
(ccBSM)
Under Empower, or MassLynx software control, the pump’s A side
actively chills the CO2fluid pumped into the system while the pump’s
B side can pump any one of four co-solvents. The pump operates at
flow rates up to 4 mL/min and pressures up to 41,369 kPa (413 bar,
6000 psi).
ACQUITY UPC2
Photodiode array (PDA)
detector
Incorporates a 10-mm stainless steel flow cell that can withstand
pressures as high as 41,369 kPa (413 bar, 6000 psi). Updated lens
material improves sensitivity and performance. Reduced internal
volume in the flow cell minimizes dispersion within the cell.
Side-mounted solvent
tray Provides easy access to the solvent bottles in an ACQUITY UPC2
system.
Top-mounted solvent tray The optional top-mounted solvent tray is available for configurations
of four or fewer modules in a stack.
