Adsorbosil columns are high-performance HPLC columns based on classical fully porous silica materials. Engineered for consistent and reproducible chromatographic performance, they are an ideal choice for routine reversed-phase, normal-phase, and HILIC separations.
With a broad range of surface modifications such as C18, C8, C2, CN, NH₂, Phenyl, and Si, Adsorbosil offers flexible selectivity and robust performance across various analytical fields. Whether in pharmaceutical quality control, food and beverage testing, or environmental analysis – Adsorbosil delivers reliable results and excellent column stability.
The product line was aquired by Dr. Maisch HPLC GmbH in 2016 from Grace / Alltech.
Good alternative to Polygosil® - MACHEREY-NAGEL.
