Ion Chromatography (IC) Acrodisc® Syringe Filters

Optimized to Provide the Most Consistent Results when Analyzing Ionic Species

• Acrodisc PSF syringe filters are Zymark* and SOTAX* Automation Certified to assure smooth operation and worry-free performance 24 hours a day in automated workstations.
• Accurate results for the most sensitive analysis of ionic species. Certified for low levels of extractables detected by conductivity.
• High flow rates with optimized Supor® polyethersulfone membrane.
• Conforms to quality release criteria for ion chromatography (IC) extractables.
• Convenient sizes for small sample volumes. 

*Registered trademark

• Specifically designed for IC applications.
• Excellent filter selection for dissolution samples.
• Low drug and protein binding for pharmaceutical filtration.
• Supor (IC) membrane discs are recommended for aqueous samples only.
• 25 mm Acrodisc PSF syringe filter is available in robotic-compatible packaging for Caliper*, TPW*, APW* and Multi-Dose* systems, and Sotax* dissolution systems.
• New 0.2 µm Acrodisc syringe filters are optimized for UHPLC sample preparation.

Ion Chromatography Certification

Pall Life Sciences certifies that the maximum allowable levels of extractables from the filter are 50 ppb of CI^- , NO₃^- , and SO₄^-2 . Data shows that the actual background levels found are typically less than 20 ppb for chloride, 6 ppb for nitrate, 1 ppb for phosphate, and 10 ppb for sulfate. This is based on 2 mL of H₂O filtrate being concentrated on-line and injected into an ion chromatograph with conductivity detection.
