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.
