The minimum achievable column compartment temperature set point
Note:
cannot be greater than 25 °C below ambient temperature.
A supplementary pre-heating device (active preheater) can also be installed,
to heat the incoming solvent before it enters the column.
The column manager also offers a bypass channel and automated,
programmable switching between columns for methods development.
ACQUITY UPLC™ columns are equipped with eCord Information
Management Technology, which captures the history of each column to assist
in tracking column usage. Reusable high-pressure fittings ease replacement of
the columns, when needed.
The column manager can accommodate columns with inside diameters of up
to 4.6 mm. It can accommodate two 100- or 150-mm columns or four 50-mm
columns.
Receptacles on the column manager's front panel receive the column eCord™
chips. The eCord column chip stores column manufacturing and usage data,
which you can access from the ACQUITY UPLC Console.
