Rapid, Reliable, and Accurate Analysis
Characterizing proteins, nanoparticles, and polymers confronts the user with a difficult choice of instrumentation. Brookhaven Instruments makes that choice easier with the NanoBrook series of instruments. Choose from particle sizing including backscatter for proteins, Zeta Potential, or combinations including molecular weight determination of small polymers and proteins.

 

Measurement Principles
Principles of Operation – Sizing
Dilute suspensions, on the order of 0.0001 to 1.0% v/v are prepared, using suitable wetting and/or dispersing agents, if required. A small ultrasonicator is sometimes useful in breaking up loosely held agglomerates. At 173° sample volume may be reduced to 50 µL with a polystyrene, U-shaped, disposable cuvette and the sample is recoverable. At 90° square polystyrene or glass cells (two or three mL) are used, one as small as 10 µL (non-disposable). In addition, disposable, glass round cells with reusable Teflon stoppers are used for aggressive solvent suspensions. In all cases, just a few minutes are required for the sample and cell to equilibrate with the actively controlled temperature environment inside the NanoBrook.

Typical Applications Include:

  • Proteins, IgG, peptides, RNA/DNA
  • Liposomes, exosomes, and other biocolloids
  • Polysaccharides
  • Nanoparticles
  • Polymer latexes
  • Pharmaceutical preparations
  • Micelles
  • Oil/Water and Water/Oil emulsions
  • Paints and pigments
  • Colloids
  • Polymers
  • Pigments, inks and toners
  • Cosmetic Formulation
  • Ceramics and refractories
  • Emulsions (foodstuffs, cosmetics)
  • Wastewater treatment monitoring
  • Carbon blacks
