WebReversed phase is very similar to non-chiral type RP applications, where increasing the water content increases retention (except for some amino acid applications, when it is the reverse). It is also ideal for LC/MS methods. Finally, normal phase, representing about 15% of all separations, uses typical hexane or heptane-alcohol mixtures and has ... WebDiscovery ® HPLC columns are efficient for the analysis of biomolecules and small molecules. These columns have polar and non-polar bondings, with unique retention, selectivity, and no-bleed properties for LC-MS applications. The Ascentis ® bonded phases have a wide range of selectivity. Type B silica makes the column inert, stable, and ...
