5.11.2 Operation Suppressor
Note
The suppressor units must never be regenerated in the same flow direc-
tion in which the eluent is pumped. Therefore, always mount the inlet
and outlet capillaries according to diagram outlined in (see "Connecting
the capillaries of the suppressor", page 52).
The suppressor consists of 3 suppressor units, which are in rotation used
for suppression – regenerated with regeneration solution – rinsed with
ultrapure water. In order to record every new chromatogram under com-
parable conditions, you should normally work with a freshly regenerated
suppressor unit.
Caution
The suppressor must never be switched over in a dry state, as there is a
risk of jamming. If the suppressor is in a dry state, it must be rinsed for
at least 5 minutes before it may be switched over.
Caution
In the case of reduced capacity or high backpressure, the suppressor
must be regenerated (see Chapter 5.11.3.2, page 83), cleaned (see
Chapter 5.11.3.3, page 85) or replaced (see Chapter 5.11.3.4, page
86).
