EC HPLC column (analytical), NUCLEOSIL 100-7 C6H5, 7 µm, 250x4 mm Gradation - QUAT - 0 • 10 • 25 • 50 • 100 • 250 • 500 • 1000  mg/L Benzalkonium chloride Di-n-propylsulfideRelatively nonpolar phase for RP and ion pairing chromatography. Polarity similar to C8, but with different selectivity for polycyclic aromatic hydrocarbons, polar aromatics, fatty acids etc. Separation mechanism based on interactions and hydrophobic (van der Waals) interactions, some residual silanol interactions. Based on the original NUCLEOSIL silica gel. It is one of the first spherical silicas for HPLC and was originally developed by MACHEREY
