ASM 2.1L user manual V6815
Device overview
6
the pumps high pressure flow, so that the sample is transported to the
column.
Multiposition valves with 6 ports and 8 ports
Multiposition valves are used to switch fluid streams, e.g. the selection
of eluents, columns or for fractionating of eluate. Bioninert valve heads
are available.
Valve heads available for different applications in UHPLC, analytical
HPLC and preparative HPLC.
Different valves of the company VICI Valco Instruments Co.Inc. can be
installed.
Valve drives 6V, 12V, 16V availabe.
Degasser
The usage of a degasser in front of the pump leads to a stable baseline
of the chromatogram.
Eluents must not be degassed before they be used in the HPLC.
Analytical flow rate up to 10 ml/min
Detector and flow cells
The ASM 2.1L can be equipped with a detector on the left side. The
UVD 2.1S will be delivered with a test cell. For the use of the detector, a
flow cell has to be installed. For further information, take a look into the

Flow cells
Flow cells are available with different path lengths, connections and also
for different maximum flow rates. The flow cells are made of stainless steel
or PEEK.
Pump and pump heads
The ASM 2.1L can be equipped with a pump P 2.1S/P 4.1S. The pump
P 4.1S is equipped with an additional pressure sensor. For further infor-
mation, take a look into the
