3.14 Sample preparation module (SPM)
3.14.1 Fields of application
The SPM consists of 3 neutralization units in total, which are used, regen-
erated and rinsed in rotation for sample preparation.
It can be used for the following applications (amongst others):
￭ for cation exchange before feeding the sample (see "Cation
exchange", page 48).
￭ for the neutralization of a sample (see "Neutralization", page 49).
3.14.2 Connectors
Caution
To protect the SPM against foreign particles or bacterial growth, a
pump tubing connection with filter (6.2744.180) must be mounted
between the peristaltic pump and the inlet capillaries of the SPM.
The three inlets and outlets of the neutralization units numbered 1..3 on
the SPM each have 2 fixed mounted PTFE capillaries (see Figure 24, page
47).
