ACE® Excel C18-PFP 2 µm UHPLC columns use a proprietary bonding and end-capping process to produce a very rugged and robust octadecyl-perfluorophenyl (C18-PFP) phase.
ACE® Excel C18-PFP offers multiple types of analyte-stationary phase interactions (hydrophobic, pi-pi, dipole-dipole, and hydrogen bonding) to deliver unique selectivity, complementary to that of the ACE® Excel C18-AR. The ultra-inert characteristics of the ACE® Excel C18-PFP Columns make them the ideal choice for separating analytes that differ in hydrophobicity, electron-rich analytes with electron delocalization and electron donating groups (i.e. phenols, aromatic ehters, and amines). Recommended applications for sterioisomers, steroids, taxanes, substituted aromatics, and nucleosides. ACE® columns consistently produce measurably better peak shape and column efficiency when separating troublesome compounds. ACE® Excel C18-PFP is also compatible with 100% Aqueous mobile phases for enhanced retention in reversed phase mode.
ACE® Excel C18-PFP is available in 2, 3 and 5 µm particles sizes. ACE® Excel C18-PFP has a surface area of 300 m²/g and a carbon load of 14.3%. ACE® Excel C18-PFP has a recommended pH range of 2 to 8 (working outside these ranges will reduce column lifetime).
ACE® Excel UHPLC columns are extremely robust even when operated at high pressures and temperatures. ACE® Excel 2 µm columns are packed at extreme pressures in specialized hardware. They can be operated at pressures as high as 1,000 bar. A specially engineered 2 µm inlet frit makes them less prone to plugging than conventional UHPLC columns. ACE® Excel columns are compatible with all HPLC, UPLC and UHPLC instruments.
Ordering information: ACE® Excel 2 µm UHPLC columns currently do not have a guard column system. Manufacturer highly recommends UltraShield pre-column filters.
