Streaming Potential Zeta Analyzer for Solid Surfaces

固体表面流动电位 Zeta 分析仪

Membranes, fibres, implant coatings and films cannot be suspended in a cuvette, so their surface charge is measured by streaming potential. Flat samples from 10 × 20 mm up to 20 × 50 mm form a gap of about 100 µm, through which electrolyte flows at up to 600 mbar. Readings span −200 to +200 mV over pH 2–12 using Ag/AgCl electrodes.

Product Description 产品描述

Membranes, fibres, implant coatings and films cannot be suspended in a cuvette, so their surface charge is measured by streaming potential. Flat samples from 10 × 20 mm up to 20 × 50 mm form a gap of about 100 µm, through which electrolyte flows at up to 600 mbar. Readings span −200 to +200 mV over pH 2–12 using Ag/AgCl electrodes.

Highlights

  • Measures charge on flat solids, fibres and powders
  • Adjustable gap of about 100 µm
  • pH scans 2–12 with electrolyte at 0.1–100 mS/cm
  • Streaming potential or streaming current modes

Applications

  • Reverse osmosis and ultrafiltration membrane charge
  • Textile and natural fibre surfaces
  • Biomaterial and implant coatings
  • Glass and polymer films
  • Powder catalysts and minerals
