Grom Resin H+, IEX is a polymer-based HPLC column functionalized with sulfonic acid groups in the hydrogen form (H⁺). It is designed for ion-exclusion chromatography (IEC) and is ideal for the separation of organic acids, alcohols, sugars, and other hydrophilic compounds using simple aqueous mobile phases. Thanks to its silanol-free polymer matrix, it offers outstanding pH stability, low column bleed, and excellent reproducibility – even under highly acidic conditions.
This column is a trusted tool for robust and routine analysis in food, beverage, biofermentation, and environmental testing.
Grom Resin H+, IEX combines chemical robustness with high selectivity – the perfect solution for reliable ion-exclusion HPLC in demanding analytical environments.
Key Features:
Strong cation exchanger in H⁺ form for ion-exclusion separations
Cross-linked polymer with broad pH stability (typically pH 1–13)
Ideal for sugar, organic acid, and alcohol analysis
High compatibility with RI, UV, and conductivity detection
Long column lifetime and low maintenance under aqueous conditions
Typical Applications:
Analysis of organic acids in food and fermentation products
Quantification of sugars and polyols in beverages
Alcohol profiling in bioprocessing and QC
Ion-exclusion chromatography of weakly ionized compounds
