Ultra Uniform materials have the most strongly monodispersed particles and are ideal for use as size standards or in applications requiring precise size dispersion.
The Ultra Uniform Particle Number Standards offer extra characterization and meticulous formulation for applications that need a specific particle number concentration.
The metal surface is covalently linked to PEG-carboxyl. The acid can be used for conjugation since it offers an extremely negatively charged surface.
The materials are provided at 108 particles/mL in aqueous 1 mM sodium citrate.
Applications
- TRPS: Tunable Resistive Pulse Sensing
- sp-ICP-MS: Single Particle Inductively Coupled Plasma Mass Spectroscopy
- NTA: Nano Tracking Analysis
