2 Injection and sequential suppression
■
The injection valve is switched to the position Inject.
■
With the eluent flow (26-2) the sample prepared is rinsed onto
the separation column (26-C).
■
The sequential suppression with the MSM-HC (26-D) and the
MCS follows after the separation.

Neutralization
A typical use of the SPM is the neutralization of an alkaline sample for
anion determination with chemical suppression.
