PerfectSil™ Target, manufactured by MZ-Analysentechnik GmbH, Germany, are high-quality HPLC columns for challenging analyses. The base material is an ultra-pure, spherical silica gel. PerfectSil™ Target HPLC columns show excellent peak symmetry  - even for basic compounds and exhibit a very high chemical and mechanical stability. Due to a special end-capping, the silica surface is effectively shielded against unwanted silanol-analyte interactions. The columns are manufactured under ISO 9001 certified conditions and are well suited for LC-MS applications. Each column are individually tested to ensure top-quality.
