Deactivated capillary columns, precolumns, Phe-Sil, low–medium polar QuEChERS Method - Clean-up AOAC 2007.01 PP cap only up toDeactivated capillary columns (precolumns) with phenylmethyl (low medium polar) surface for protection of the analytical column against contamination and extend its lifetime. Me Sil is more inert than Phe Sil, while Phe Sil is less susceptible to contamination. Technical Data Downloads Macherey Nagel Chromatography Catalogue
