TEM Diameter | Size Distribution (CV) | Example Certificate of Analysis(How do I read this?) |
---|---|---|
40 nm ± 4 nm | ≤ 15% | Download Example CoA |
80 nm ± 5 nm | ≤ 15% | Download Example CoA |
Note: approximate ranges below are dependent on diameter
- Hydrodynamic diameter (DLS): TEM diameter plus 0 to 10 nm
- Zeta potential: –25 to –80 mV
- pH of solution: 5.5 to 8.5
- Particle surface: citrate
- Solvent: Milli-Q water for 40 nm, aqueous potassium carbonate for 80 nm
- Peak wavelength (λmax): 520 to 530 nm
