Question

Which Shodex columns are suitable for analyzing organic acids, polysaccharides, sugar alcohols, glycerin, and ethanol in fuel ethanol industry samples?

Answer

Shodex offers several column options for common analytes in the fuel ethanol industry (e.g., organic acids, polysaccharides, sugar alcohols, lactic acid, glycerin, ethanol):

• SUGAR Series (USP L22, cation-exchange resin, Pb²⁺ or H⁺ form):

  • Columns: SP0810, SC1011, SC1211, SH1011, SH1821, SZ5532, KS-800 series

  • Applications: saccharides, sugar alcohols, organic acids, ethanol

• NH2P-50 4E (Polymer-based Amino HILIC):

  • Mode: Hydrophilic interaction chromatography

  • Compatible with acetonitrile/water eluents, LC/MS compatible

  • Applications: saccharides, phosphorylated sugars, amino sugars

• Size Exclusion (SEC):

  • Columns: KS-800 and SB series

  • Applications: polysaccharides, glycans, degradation products, high-MW components in biofuels

  • Allows for broad one-step profiling, including polysaccharides and ethanol-related metabolites

Summary:
For comprehensive analysis of fuel ethanol matrices:

• Use SUGAR series for sugars, organic acids, and alcohols.

• Use NH2P series for saccharides with LC/MS compatibility.

• Use SEC (KS/SB series) for polysaccharides and larger components.
