contaminants from the solvent component of the eluent which are not removed by the Anion AutoRegen Regenerant Cartridge
may slowly accumulate in the regenerant. This results in slowly increasing background conductivity. The rate at which the
background conductivity increases versus the required analysis sensitivity will determine how often the regenerant must be
changed.
It is not necessary to change the Anion AutoRegen Regenerant Cartridge until it is completely expended and a sudden jump to
very high background conductivity is observed.
3.11 Using Displacement Chemical Regernation (DCR) with the Chemical Suppression Mode
DIONEX recommends using the Displacement Chemical Regeneration (DCR) Mode for chemical suppression using sulfuric acid
and the Anion MicroMembrane Suppressor (AMMS III). See the DCR kit manual, Document P/N 031664, for details.
SAFETY
Use proper safety precautions in handling acids and bases.
3.12 Detector Requirements
See Section 2, “The Ion Chromatography System,” for 4-mm system detector, cell and thermal stabilizer requirements.
