DIONEX AS 50 is a hydrophilic polymer-based stationary phase, and it is a common choice amongst high performance liquid chromatography (HPLC) users. This stationary phase is often used to separate and identify the components in bio-, environmental-, and chemical-samples. AS 50 is made of a porous hydrophilic polymer with a diameter of 5 um. This material is able to retain compounds with different physical and chemical properties. It is one of the few stationary phases that can be combined with several elution buffers, that also helps to provide a wide range of separations. DIONEX AS 50 has a high resolving power, so it is suited for resolving complex chromatographic samples. The stationary phase has an average pore size of 10 to 12 Å, and this size allows the direct elution of large molecules. At the same time, this feature also minimizes the amount of column bleeding. The presence of surface-bound organosilane groups on the stationary phase helps maximize the retention of hydrophobic compounds. Furthermore, the surface-bound groups enhance the adsorption process and the loading capacity of AS 50. DIONEX AS 50 is manufactured with the highest quality standards to guarantee a high performance level. The stationary phase is easy to use and it can resist a wide range of temperature changes, from -40 °C to +125 °C. Therefore, this stationary phase is also suitable for reversed-phase systems and for the separation of polymers. AS 50 requires minimal maintenance and it is a long-term choice if compared with other, cheaper stationary phases. However, very volatile compounds such as alcohol, hydrocarbons, and chlorinated compounds could be difficult to separate and optimize. Additionally, some compounds, especially those with small molecular sizes, require higher temperatures to elute the compounds. Overall, DIONEX AS 50 has proven to be a reliable stationary phase for HPLC applications. The stationary phase is made of high quality material that provides reliable separations with minimal maintenance.
