5μm and 5μm solid-core particles • superc18 and superphenylhexyl phases with extended ph stability ace ultracore superc18 and superphenylhexyl phases are manufactured using our unique encapsulated bonding technology (ebt™)additionally, ace c18-ar is suitable for use in highly aqueous (up to 100%) mobile phases to enable the retention and separation of polar compoundsace c18-amide is a uniquely designed polar-embedded stationary phase offering improved retention of polar compounds, enhanced phenolic resolution and alternative selectivity to c18 bonded columnsnow available with solid-core particles ace ultracore is an addition to the ace range of bonded phases, ultra-inert solid-core phase manfactured using the unique encapsulated bonding technology (ebttm)the higher ligand coverage results in improved inertness, chromatographic performance and stabilitythis technology dramatically increases ligand coverage of the silica surface and effectively eliminates the negative effects of unbonded silanol groupsultra-high purity, ultra-inert ace columns also provide unmatched reproducibility and excellent column lifetimethe longer c18 tail of the ligand increases the hydrophobic mechanism of interaction compared to phases with shorter (c14 – c16) tail groupsit is useful for analytes with electron withdrawing and delocalised systems such as nitro groups, ketones, esters, acids and aromatic compoundslc/ms to preparative scale dimensions 3ultra inert base deactivated hplc columns ace c18 hplc column ace c18 is the optimum and most versatile starting point for most method development activitiesthe special design of the ace c18-amide ligand incorporates an extended alkyl chain spacer between the silica surface and amide polar group, which gives extra phase stability in eluents of ph 2 – ph 8ace hplc columns ace hplc columns are designed to meet even the most challenging of chromatographic applications, giving excellent performance with acidic, basic and neutral moleculesindependent comparison tests show ace hplc columns give outstanding performanceace c18-amide offers low bleed for uv and lc-ms compatibility and can be used in 100% aqueous mobile phase conditionsace c18-pfp combines the hydrophobic characteristics of a c18 phase with the alternative selectivity offered by a pentafluorophenyl phase, providing pi-pi, dipole-dipole, hydrophobic and shape selectivity mechanismsa wide range of particle sizes, pore sizes, bonded chemistries and column dimensions are availableit offers ultra-inert silica for superior peak shape and guaranteed batch-to-batch and column-to-column reproducibilityace c18-ar combines the hydrophobic characteristics of a c18 phase with the enhanced aromatic selectivity of a phenyl phase, allowing the benefits of both interactions to be fully exploited• ultra-inert solid-core uhplc / hplc columns • high efficiency 2this phase is recommended for polar to mid-polar analytesthis phase is stable in 100% aqueous mobile phase conditions, exhibits ultra low bleed to ensure lc-ms compatibility and demonstrates excellent temperature and ph stabilityace c18 provides hydrophobic interactions and some shape selectivity for general reversed-phase applications and analytes including those differing in hydrophobicity, uncharged acids and bases, polar to non-polar analytes and ionised acids and bases (using ion-pair chromatography)the phase also exhibits ultra low bleed to ensure lc-ms compatibility and demonstrates excellent temperature and ph stabilityace ultracore the advantages of ace uhplc/hplc columnsace c18-pfp is ideal for halogenated analytes and analytes with electron donating groups such as phenols, aromatics, ethers and amines and is additionally useful for regioisomersguaranteed reproducibility 2
