HPLC


Excellent Resolution and Reproducibility

Rezex™ HPLC ion-exclusion columns achieve reproducible, accurate separations based on multiple modes of interaction. Available in 4 % and 8 % cross-linked sulfonated styrene-divinylbenzene (SDVB) and multiple ionic forms for a wide range of selectivities. USP L17, L19, L22, L34, and L58 packings available.

Use Rezex for carbohydrate, oligosaccharide, and organic acid separations:

  • bioethanol monitoring
  • drug formulation and excipient analysis
  • food and beverage quality control testing

*Recommended alternative to Bio-Rad® Aminex®, Supelco® SUPELCOGEL™, and Waters® Sugar-Pak™

Technical Notes Faster Real-Time Response to Bacterial Infection of Bioethanol Fermentation using a Short Rezex™ ROA Column

Summary

Today, many ethanol producers are looking for ways to reduce cost and improve operational efficiency. A quick and easy way to achieve this is by using the shorter Rezex ROA 150 x 7.8 mm column as an alternative to a longer 300 x 7.8 mm column. The shorter column will not only increase throughput by 50 %, but also reduce cost by utilizing less solvent for each HPLC run.
