Phase Analysis Light Scattering Zeta Potential Analyzer

相位分析光散射 Zeta 电位分析仪

Antibody formulations, high-salt buffers and oil-based dispersions give weak, noisy mobility signals on conventional instruments. Phase analysis light scattering with field reversal resolves mobility down to 0.005 µm·cm/V·s while applying a gentle 5–20 V/cm field that limits sample heating. Conductivity up to 200 mS/cm is accepted. Specify a 633 nm or 660 nm laser.

Mobility range
±20 µm·cm/V·s
Mobility sensitivity
≤ 0.005 µm·cm/V·s
Zeta potential range
−500 to +500 mV
Measurement principle
PALS with field reversal
Laser

Product Description 产品描述

Antibody formulations, high-salt buffers and oil-based dispersions give weak, noisy mobility signals on conventional instruments. Phase analysis light scattering with field reversal resolves mobility down to 0.005 µm·cm/V·s while applying a gentle 5–20 V/cm field that limits sample heating. Conductivity up to 200 mS/cm is accepted. Specify a 633 nm or 660 nm laser.

Highlights

  • Mobility sensitivity of 0.005 µm·cm/V·s or better
  • Low applied field of 5–20 V/cm protects proteins
  • Copes with physiological and high-salt media
  • Works with non-aqueous samples in oils and alcohols

Applications

  • Protein and monoclonal antibody formulation
  • Samples near the isoelectric point
  • High-salt buffers and physiological media
  • Non-aqueous dispersions in oils and alcohols
  • Liposome and lipid nanoparticle studies
