Aminex HPLC Columns

Description

Aminex HPLC columns from Bio-Rad are designed for high-performance liquid chromatography, utilizing a stationary phase composed of a polymer-based matrix. This matrix is typically a cross-linked polystyrene divinylbenzene resin. The separation mechanism is based on size exclusion principles, where molecules are differentiated according to their hydrodynamic volume as they pass through the porous polymer network. These columns are suitable for analyzing a range of compounds, including organic acids, alcohols, and carbohydrates. The polymer packing material offers chemical stability across a wide pH range, providing durability for routine analytical applications. Users should select the specific column model based on the target analytes and the required separation conditions.
