Adsorbosil C2 features a short carbon linker bonded phase on high-purity, fully porous silica and is specifically designed for the separation of highly hydrophobic compounds or early-eluting polar analytes. Due to its low carbon load and minimal hydrophobic interaction, this phase is ideal for cases where classical C18 or C8 columns provide excessive retention or poor resolution.
The Adsorbosil C2 phase offers high reproducibility and excellent column stability, making it a reliable tool for both routine and specialized applications in reversed-phase chromatography.
Adsorbosil C2 is the optimal reversed-phase HPLC column for low-retention separations, offering unique selectivity where traditional C8/C18 columns fall short.
