Grom Resin

Polymer-Based HPLC Columns for pH-Stable and Specialized Separations

Grom Resin is a group of polymer-based HPLC columns engineered for high chemical stability across a wide pH range, making them ideal for challenging separations that involve extreme pH, aggressive mobile phases, or highly polar analytes. Unlike silica-based materials, Grom Resin phases are built on cross-linked polymer particles, ensuring mechanical robustness, long column lifetime, and versatile selectivity options such as reversed-phase and ion-exchange modes.

Specifications

Particle Sizes 8 µm

Key Features:

  • Polymer-based stationary phases with high pH resistance

  • Suitable for reversed-phase and ion-exchange chromatography

  • Free of silanol interactions – ideal for basic compounds

  • Stable under acidic, neutral, and basic mobile phase conditions

  • Available in particle sizes such as 5 µm and 10 µm

Application Focus:

  • Analysis of ionizable and highly polar compounds

  • LC methods under extreme pH or aggressive solvents

  • Method development where silica columns are unstable

  • Food, pharmaceutical, and specialty chemical separations

Grom Resin columns offer durable and flexible chromatographic performance – ideal for laboratories needing pH-stable alternatives to traditional silica-based HPLC columns.
