This high-capacity suppressor supports almost all analytical IC applications and can be used for anion and cation analysis. It is available in 2 mm and 4 mm sizes. Dionex ERS 500e suppressors are available in standard bore (4 mm) and micropore (2 mm) formats for isocratic or gradient applications of carbonate (isocratic only), hydroxide, methanesulfonic acid or sulfuric acid eluents application.

• Due to its high backpressure tolerance (no leakage up to 900 psi , operates at up to 200 psi), improving compatibility with hyphenated detection technologies (especially mass spectrometry)
• Higher temperature tolerance (up to 80°C during transportation and storage, 40°C during operation)
• With its flat packed bed suppression tank and complete electrolytic regeneration design without reagents, it can be easily restored after no-current operation
• Low peak dispersion maintains peak shape efficiency of 4 µm columns
• High suppression capacity produces stable peak area values immediately after restart without chemical regeneration
• Low Noise characteristics make the suppressor suitable for trace analysis

• Reduced back pressure in the regeneration chamber facilitates pressurized storage Liquid tank delivery.
• Parallel regeneration flow maximizes regeneration removal of borate eluents and eluents containing organic solvents (up to 40%).
• Can be used in chemical regeneration mode.

When used with the Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device, the Dionex ERS 500e Suppressor Under eluent conditions, it can reduce background conductivity and noise, enhance analyte response, and improve sensitivity, thereby improving the reliability of quantitative determination.

• Complete regeneration without reagents

Dionex ERS 500e The suppressor is a direct replacement for the Thermo Scientific™ Dionex™ SRS™ 300 self-regenerating suppressor.
