ACE Excel UHPLC reusable column connectors are recommended as a universal fitting suitable for connecting columns to all UPLC and UHPLC systems.
ACE Excel UHPLC Columns are designed to take full advantage of low dispersion, ultra-high pressure UPLC® & UHPLC instruments, the introduction of ACE Excel UHPLC columns gives chromatographers more choices to achieve better results.
Ultra robust columns – Unique phases – High efficiency 2μm particles.
C18 bonded phases are the most popular phases for HPLC/UHPLC because they offer good retention and selectivity for a wide variety of sample types. In addition, they are perceived to be more rugged and reliable than other bonded phases. C18 bonded phases depend mainly on hydrophobic interactions (and occasionally shape selectivity) to achieve satisfactory separations. Although versatile, C18 phases offer a limited number of separation mechanisms and this may lead to less than optimum separations in some cases and complete lack of resolution of important peak pairs in others.
ACE columns have led the way in offering C18 bonded phases with the advantage of ‘extra selectivity’. C18-AR and C18-PFP bonded phases have proved to be extremely powerful tools to use in leveraging this ‘extra selectivity’ to achieve separations that may not be possible with ‘standard’ C18 bonded phases. These ‘extra selectivity’ phases are not meant to replace ‘standard’ C18 bonded phases, but rather complement them and so provide chromatographers with powerful, additional mechanisms of separation that can be used to achieve better overall chromatographic results. The introduction of ACE Excel UHPLC columns means that chromatographers now have more choices within their reach to achieve better results with their UPLC and UHPLC instruments.
ACE Excel UHPLC columns are designed to be fully compatible with all commercial UPLC® & UHPLC instruments and have been engineered to benefit from the high flow rate, ultra-high pressure and low dispersion of these systems. ACE Excel columns provide chromatographers with more column choices so that even more value can be obtained from their UPLC/UHPLC instruments.
Owing to the optimal 2μm particle size and a rigorous classification protocol, column back pressure is significantly lower than for traditional UPLC & UHPLC columns packed with <2μm particles. Therefore ACE Excel 2μm columns may also be used on HPLC systems to provide a performance boost compared to standard HPLC columns, subject to HPLC system pressure limitations.
