Description

General description

SUPELCOGEL 8 Column Series (manufactured with 8% XL PS-DVB):
The majority of columns on the market for the analysis of carbohydrates, organic acids, and alcohols, such as Aminex^®, utilize an 8% XL PS-DVB. The 8% polymer offers excellent separation of many common samples.
Advantages: 8% polymers combine durability and good resolution. Due to higher cross-linking than 6% XL polymers, columns packed with 8% polymer can be used at higher flow rates therefore decreasing analysis times.
Disadvantages: 8% polymers are limited in separating carbohydrates larger than trisaccharides due to lower MW exclusion limits. Compared to the 6% XL polymer, for some types of carbohydrate and organic acid mixtures, the 8% shows less resolution due to selectivity differences.

Molecular Weight Exclusion Limit: 1200
Minimum Wet Capacity meq/ml: 1.7 - 1.9
Flow Rate Recommendation: 0.4 - 1.2 ml/min
