Note:
Only use the device for applications that fall within the range of the
intended use. Otherwise, the protective and safety equipment of the
device could fail.
Assistant ASM 2.1L
The Assistant ASM 2.1L is a compact combination module which is used in
analytical, preparative and continuous liquid chromatography. The con-
cept of flexible combination of device modules combines highest func-
tionality with minimal space requirements.
Equipped with up to three modules the assistant fulfills different custom-
ized or preset tasks like sample and buffer selection, sample injection, col-
umn switching, fraction collection. A selection of four different device
types is available: valve, pump, UV detector, degasser. Depending on the
selected modules the assistant is either a stand-alone compact system or
a part of an advanced system.
Compact HPLC
With a suitable selection of micro devices the ASM 2.1L can be used as a
supplementary module for the HPLC or it can be combined to a compact
HPLC system for chromatographic analyses in the high pressure range.
Operating range
The device can be used in the following areas:
Biochemistry analyses
FPLC/Biopurification
Chemical analyses
Food analyses
Pharmaceutical analyses
Environmental analyses
Eluents
Small quantities of substances such as additives, modifiers, or salts can
influence the durability of the materials. For further reference on chemical
compatibility, please consult the user manuals of the integrated devices
(see “Device overview” on page 5).
Device overview
As an additional module for the HPLC system, the ASM 2.1L can be
equipped with different devices on request. If the ASM 2.1L is delivered
with 2 micro devices and if the left position from front is left empty, the
micro device located in the central position is represented as left device in
the software packages.
Following devices can be integrated:
Detector UVD 2.1S
Small variable single wavelength UV detector
A wide range of flow cells for analytical or preparative LC applications
with flow rates from 10 μl/min to 10 l/min.
Automatic recognition and storing of device-specific information,
which are important for Good Laboratory Practice, operation qualifica-
tions, or repairing the device.
Pump P 2.1S/P 4.1S
Dual-piston technology
Liquid transport with stable flow rate and high flow accuracy
Long service life
10 ml and 50 ml pump head selectable
With or without pressure sensor
As a material for the pump head interior titanium or stainless steel can
be chosen. For the 10 ml pump head ceramic can be chosen.
Valves
The valves fall into different categories:
2-position valves with 6 ports and 8 ports
2-postion valves are used to inject the sample from the sample loop in
