GPC Column Recommendation for ~100 kDa Polymers Using DMF

Record: 672

Category: Column Selection
Product: KD-803
Sample: Polymer

Question
A customer is analyzing a polymer with an approximate molecular weight of ~100 kDa using dimethylformamide (DMF) as the solvent. Do you have a Shodex column recommendation?

Answer

Yes. For gel permeation chromatography (GPC) analysis of polymers with molecular weight around 100 kDa using DMF as the mobile phase, Shodex KD-803 is a suitable choice.

KD-803 is a polymer-based GPC column designed for use with DMF and other compatible polar organic solvents and provides an appropriate pore size for molecular-weight distribution analysis in this range. It is commonly used for synthetic polymer characterization under standard GPC conditions with refractive index or other compatible detectors.

Recommended Application:

• Calibration Curves for KD-800 Series (DMF Eluent, PMMA)
  Provides molecular-weight calibration ranges for KD-800 series columns using DMF, supporting selection of KD-803 for polymers around 100 kDa.
