Does Waters sell a polymer standard with a well-defined hydrodynamic volume of 2-5 nm? - WKB227687
Article number: 227687
ENVIRONMENT
- Polymer standards
- Particle size analyzers
ANSWER
No. Waters sells polymer standards for molecular weight calibration.
The hydrodynamic radius would be affected by the solvent used to solubilize the standard. Even narrow standards would have a size distribution.
ADDITIONAL INFORMATION
Companies that sell or make particle size analyzers may sell standards to calibrate the instrument.
