ReproSil-Pur

A robust modern and all purpose ultra high purity spherical silica media scalable from UPLC to prep. Various pore sizes are available to cover applications for small molecules up to biomolecules. State-of-the-art surface modification technologies are employed for normal and reversed phase media including shape selective, high carbon load as well as water wettable alkyl phases.

ReproSil XR

An allround and fully scaleable spherical Silica from 1.5 to 15 µm with an extra high purity. The metal content is less than 100 ppb. The silica impresses with its very narrow pore size distribution this make 99 % of the surface accessable for the separation. The uniform bonded phase coverage translates to symmetrical peaks for acids/bases, and predictable reversed phase selectivity. Because of its very low metal content it also impressed with a high pH stability.

Ultrasep

The company SepServ with the Ultrasep ES column line was founded by G. J. Eppert and I. Schinke in Berlin. The philosophy of the company was to be a bridge to solve problems with its experience. G. J. Eppert developed many different modifications for specialized applications in 40 years. Dr. Maisch HPLC GmbH bought the company SepServ in 2014 and has been continuing the production of the ultrasep columns since then.
