This application note describes how to analyze polyvinyl pyrrolidone (PVP) samples using Agilent Technologies PLgel 10 µm MIXED-B columns.
The document details an analytical method for determining the molecular weight distribution of polyvinyl pyrrolidone (PVP). A sample found to be soluble in dimethylacetamide was analyzed using Agilent PLgel 10 µm MIXED-B columns. To minimize polyelectrolyte effects, lithium chloride was added to the eluent.
| Molecular Weight Range | up to 10 million |
|---|---|
| Particle Size | 10 µm |
| Column Dimensions | 300 x 7.5 mm |
| Flow Rate | 1.0 mL/min |
| Temperature | 60°C |
The method uses DMAc with 0.5% LiCl added to minimize polyelectrolyte effects.
Lithium chloride is added to minimize polyelectrolyte effects during analysis.
