I. After complete neutralization, the sample is delivered to the injection valve of the
Dionex Ion Chromatography system and a low pressure trap column such as the
Dionex UTAC-XLP2 (Item # 072781) for the Dionex AERS 500e (4 mm) or Dionex
TCC-XLP1 (Item # 063889) for the Dionex CERS 500e (4 mm).
J. The trace ions are then analyzed by the Dionex Ion Chromatography system.
For detailed information on the timing and configuration of the Sample Valve, Recycle Valve,
and Injection Valve, refer to Thermo Scientific Dionex Application Note 93 or 94, or to the
Dionex SP10 AutoNeutralizer Operator’s Manual (Document Number 034980).
3.8 Dionex ERS 500, Dionex ERS 500e or Dionex AERS 500 Carbonate Storage
The Dionex ERS 500, Dionex ERS 500e and Dionex AERS 500 Carbonate are shipped with
deionized water as the storage solution. If the suppressor will not be used for more than three
days, prepare it for storage. The resin, screens and membranes in the suppressor must be
completely hydrated to maintain liquid seal and chromatographic performance. Plug all of the
ports after hydration.
3.8.1 Short Term Storage (3 to 7 days)
A. Using a plastic syringe, push 5 mL of deionized water through the REGEN IN port,
and 3 mL of Deionized Water through the ELUENT IN port until all bubbles are
removed. Plug all the ports (both REGEN and ELUENT ports).
B. To resume operation, connect the suppressor to the system. Allow the system to
equilibrate before starting analysis.
If the eluent last used contained organic solvents, flush the Dionex ERS 500, Dionex ERS
500e or Dionex AERS 500 Carbonate with deionized water for 10 minutes through both
chambers before plugging the fitting ports.
3.8.2 Long Term Storage (More than 7 days)
A. Connect the eluent and regenerant chambers in series and flush the Dionex ERS 500,
Dionex ERS 500e or Dionex AERS 500 Carbonate with deionized water for 10
minutes at 1.0 mL/min (4 mm) or 0.25 mL/min (2 mm).
B. Plug all suppressor ELUENT ports and REGEN ports.
C. To resume operation, complete the hydration steps and connect the suppressor to the
system. Allow the system to equilibrate before starting analysis.
D. If small or increasing analyte peak areas are observed, perform steps A–G as outlined
in
Section 5.2
, “Small or increasing Analyte Peak Area or Regeneration.”
