Ace Hplc Column

ACE HPLC columns are designed to meet even the most challenging of chromatographic applications, giving excellent performance with acidic, basic and neutral molecules. A wide range of particle sizes, pore sizes, bonded chemistries and column dimensions are available.
Ultra-high purity, ultra-inert ACE columns also provide unmatched reproducibility and excellent column lifetime. Independent comparison tests show ACE HPLC columns give outstanding performance.
1. Guaranteed reproducibility
2. LC/MS to preparative scale dimensions
3. Ultra inert base deactivated HPLC columns

ace c18 hplc column
ACE C18 is the optimum and most versatile starting point for most method development activities. It offers ultra-inert silica for superior peak shape and guaranteed batch-to-batch and column-to-column reproducibility. ACE 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).

ACE 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. The phase also exhibits ultra low bleed to ensure LC-MS compatibility and demonstrates excellent temperature and pH stability. Additionally, ACE C18-AR is suitable for use in highly aqueous (up to 100%) mobile phases to enable the retention and separation of polar compounds. It is useful for analytes with electron withdrawing and delocalised systems such as nitro groups, ketones, esters, acids and aromatic compounds.

ACE 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 mechanisms.
