Columns
YMCbasic is a unique reversed-phase column designed for analysis of pharmaceuticals and other basic compounds. YMCbasic utilizes a novel silica synthesis and state-of-art silane bonding to create a column which gives true reversed-phase character, high resolution and excellent peak shape for the analysis of basic compounds.
The silica support used in YMCbasic is prepared by an advanced synthetic process which yields a chromatographic material with proprietary pore size and “neutral” silanols minimize interactions with both basic and acidic compounds. The stationary phase is a monomeric bonding of several different alkyl silanes with chain length of C8 and smaller.
The “neutral” silica support used in YMCbasic exhibits minimal secondary retention interactions so selectivity is true reversed-phase. There are no special surface treatments or exotic endcapping procedures. This means that YMCbasic provides the same general selectivity seen with conventional C18 and C8 columns without basic compounds tailing.
