Function
The mixer valve module consists of a number of membrane valves. The mixer valve directs
the flow through the mixer, or by-passes the mixer, for example during sample application.
The mixer mixes the A and B buffers in a 5 mL mixer chamber to a homogeneous buffer
composition.
If the mixer is in-line, the mixer stir magnet starts and stops automatically at start and
end of a method. If it is by-passed, it does not start.
When to use
Some examples with recommendations to use the mixer or not are shown in the table
below.
CommentRecommendedExample
Strongly recommended at high salt
concentrations.
YESHIC with flow rate
< 30 mL/min
At high flow rates, the buffers are
sufficiently mixed without the need
of a mixer.
N/AFlow rate
> 100 mL/min
Set the mixer to by-pass during
sample application.
