What is a good choice of GPC standard when analyzing PVP (polyvinylpyrrolidone) in a solvent of DMF (dimethylformamide)? - WKB99912
Article number: 99912
ENVIRONMENT
- Gel permeation chromatography (GPC)
- Size exclusion chromatography (SEC)
- Gel filtration chromatography (GFC)
- Polyvinylpyrrolidone PVP
- GPC standards
ANSWER
PEG (polyethylene glycol), if soluble in DMF at low MW
ADDITIONAL INFORMATION
PEG may be soluble in 100% DMF if the PEG is in the lower MW range.
Solubility studies need to be performed to determine if the PEG MW standard is soluble in DMF.
