Eluent Storage
IonPac AS9-SC columns are designed to be used with borate or bicarbonate/carbonate eluent systems. Storage under a helium
atmosphere ensures contamination free operation and proper pump performance (nitrogen can be used if eluents do not contain
solvents).
3.7
The Anion Self-Regenerating Suppressor, ASRS® -ULTRA
An Anion Self-Regenerating Suppressor should be used for applications that require suppressed conductivity detection. It is
compatible with solvent containing eluents and aqueous ionic eluents of all concentrations with which the systems and columns
are compatible. Aqueous ionic eluents can be used in all ASRS-ULTRA modes of operation.
NOTE
Solvent containing eluents should be used in the AutoSuppression External Water Mode.
If you are installing an IonPac AS9-SC 4-mm Analytical Column, use an ASRS-ULTRA (4-mm, P/N 053946).
For detailed information on the operation of the Anion Self-Regenerating Suppressor, see Document No. 031367, the “Product
Manual for the Anion Self-Regenerating Suppressor-ULTRA, the ASRS-ULTRA.”
3.8
The Anion Atlas® Electrolytic Suppressor, AAES
An Atlas Anion Electrolytic Suppressor (AAES) may be used instead of an ASRS-ULTRA for applications that require
suppressed conductivity detection. The AAES (P/N 056116) can be used for AS9-SC 4-mm applications using eluents up to 25
µeq/min.
For detailed information on the operation of the Atlas Anion Electrolytic Suppressor, see Document No. 031770, the “Product
Manual for the Atlas Anion Electrolytic Suppressor.”
3.9
The Anion MicroMembrane Suppressor, AMMS® III
An Anion MicroMembrane Suppressor, the AMMS III (P/N 056750) can also be used for applications that require suppressed
conductivity detection. It is compatible with all solvents and concentrations with which the systems and columns are compatible.
For detailed information on the operation of the Anion MicroMembrane Suppressor, see Document No.031727, the “Product
Manual for the Anion MicroMembrane Suppressor III, the AMMS III.”
NOTE
Do not run the AMMS III Suppressor over 40°C. If you are using an application where temperatures in excess
of 40°C are required, place the suppressor outside of the oven.
To minimize the baseline shift when performing an analysis that requires a borate gradient, a high regenerant flow rate (10 - 15
mL/min) is required. To save regenerant preparation time and reduce regenerant consumption and waste, DIONEX recommends
using an AutoRegen® Accessory (P/N 039594).
3.10 Using AutoRegen® with the ASRS-ULTRA orthe AMMS III in the Chemical Suppression Mode
To save regenerant preparation time and reduce regenerant consumption and waste, DIONEX recommends using an AutoRegen
®
Accessory (P/N 039594). For more detailed information on the use of the AutoRegen Accessory see the AutoRegen Accessory
manual (Document No. 032853). For more detailed information on the use of AutoRegen Regenerant Cartridges, see the “Product
Manual for the AutoRegen Regenerant Cartridge Refills” (Document No. 032852).
When using an AutoRegen System, specific contaminants are continuously removed from the regenerant solution to restore it to
the correct ionic state. It is necessary however to replace the regenerant on a regular basis. If solvents are used in the eluent, ionic
