1.4 Multi-channel fraction collection
– multiple stream sampling
An interesting property of the LAMBDA OMNICOLL fraction collector is the option to collect
simultaneously the streams of many chromatographic columns.
For LAMBDA OMNICOLL multi-stream fraction collectors, different designs exist:
•
•
1.4.1 Standard multi-stream fraction collection
The standard multi-stream assembly is available for 2 to 18 or even more effluents of
multiple chromatography columns. This multi-stream assembly is technically very simple and
polyvalent. It allows an easy adaptation of various experimental needs directly by the user.
Examples of the standard multi-stream fraction collection:
Figure 1.4.1-1
Example of
taking 4x2 fractions in a 4-
channel configuration
Figure 1.4.1-2
Example of
taking 6x2 fractions in a 6-
channel configuration

Example of
taking 20 simultaneous
fractions in a 20-stream
(channel) configuration
