Orbit™ is the brand name for a range of HPLC columns from MZ-Analysentechnik GmbH that are specially optimized for the requirements of routine analysis. The phases are based on a high-purity and ultra-stable state-of-the-art 100Å silica gel with an almost perfect spherical particle shape and are chemically and mechanically largely inert. As a result, Orbit™ HPLC columns enable excellent chromatographic separation performance with symmetrical peaks and high reproducibility. Like all HPLC columns from MZ-Analysentechnik GmbH, Orbit™ columns are manufactured according to an ISO9001-certified process. Each column is supplied with its individual original test certificate.
