ACE® is a trademark for (U)HPLC columns of the Scottish specialist Advanced Chromatography Technologies Ltd. The stationary phases are based on spherical, high purity, ultra-inert, base deactivated silica gel. The phases are available in many, sometimes unique modifications and have a very high reproducibility. The products are manufactured according to ISO 9001: 2008 and ISO 14001: 2004. ACE® Excel are (U)HPLC columns with 1000 bar pressure stability.
