Description
For aqueous samples, polystyrene particles are often the best choice. LS Instruments offers monodisperse spherical polystyrene particles specially designed for DWS applications. In particular, the batch does not contain surfactant traces (in contrast to most other suppliers) that could contaminate your sample.
| mean diameter | 460 nm, depending on the batch (hydrodynamic size, measured by DLS and SLS) |
| PDI | <0.11 (PDI=‹d2›/‹d›2 |
| zeta potential | -80±10 mV (Smoluchowski approximation, in 10 mM phosphate buffer) |
| specific gravity | 1.05 |
| solvent | distilled water |
The particles are synthesized without surfactant to protect your sample against contamination. The production of the DWS tracer particles is outsourced, hence the average size and concentration may differ from batch to batch. Each batch is characterized separately.
| 10 mL with 8.3 wt.% particle concentration: | 210 CHF (excel. shipping cost and taxes that may apply) |
