Resin Technologies
We have established three platforms of base-bead resin technology: Silica, Polystyrene/Divinylbenzene (PS/DVB) and Polymethacrylate (PMA) with well-controlled particle sizes ranging from 1.7 to 100 µm and pore sizes from non-porous to 2000 Å. On the base beads, a broad spectrum of innovative surface modifications has been developed to meet the ever-advancing customer needs for chromatography analyses and separations. -
Column Packing Technologies
With over decades of extensive column packing experience, Sepax has developed technologies for packing a variety of LC columns, including micro with ID from 75 µm to 1.0 mm, analytical with ID from 2.1 to 7.8 mm, semi-prep and preparative with ID of 10, 21.2, 30, and 50 mm, and industrial-scale columns with ID from 50 to 800 mm. Sepax also packs FPLC columns with ID from 6.6 to 300 mm. -
Surface Technologies
Sepax has developed a broad scope of unique chemical processes for synthesizing monomeric and polymeric thin films on both flat and particle surfaces. Our unique processes allow us to make neutral, cationic or anionic coatings with a controlled thickness from a few nanometers to more than 100 nm on internal or open surface uniformly. -
Liquid Chromatography Services Capability
With more than 100 chromatographic resins and over 1000 different LC columns manufactured in house, Sepax has accumulated a broad scope of expertise to serve our customers for their various liquid chromatography needs for a wide range of small molecule and biopharmaceutical samples.
