Why Syringe Filter Selection Matters in Chromatography - Sample preparation is vital in chromatography. Filtration removes particulates before samples reach HPLC/GC systems, protecting equipment — but not all syringe filters are equal. Membrane material, pore size, and diameter all affect performance; the right choice depends on compatibility with your sample, solvent, and method, not just particle removal. Filtration is not purely mechanical, chemical compatibility is also important. Different membranes differ in compatibility, wettability, and analyte interaction. No single filter works for all applications.

eXimo Syringe Filter Membrane types: Nylon, PVDF, PTFE, Regenerated Cellulose, Polypropylene, Cellulose Acetate. Pore Sizes: 0.22 µm, 0.45 µm in 13mm, 25mm or 30mm

Simple Selection Guide
1. Sample & solvent composition
2. Membrane chemical compatibility
3. Pore size for required cleanliness
4. Diameter for sample volume
5. Cleanliness needs (extractables/leachables)

These steps ensure reliable filtration and consistent chromatography results.
