Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, announces Kinetex F5 – a robust pentafluorophenyl propyl (PFP) core-shell phase that overcomes reproducibility and performance limitations of existing PFP and F5 products on the market. After extensive internal and external testing found that existing PFP and F5 fully porous and core-shell products produced sporadic basic compound adsorption and analyte retention time shifting, Phenomenex, in partnership with customers, redefined the industry standard and developed this new core-shell pentafluorophenyl.

The new Kinetex F5 phase delivers improved reproducibility compared to other PFP or F5 columns on the market and can significantly reduce method development time with its dynamic and responsive chemical functionality. It is an ideal solution for HPLC/UHPLC development work with its combination of polar and non-polar interactions including hydrogen bonding, electrostatic, hydrophobic, aromatic and steric/planar mechanisms. Additional versatility of this phase gives scientists...

Kinetex F5 is available in 2.6 and 1.7 µm particle sizes and delivers all the advantages of Phenomenex’ Core-Shell Technology including better resolution, higher efficiency, easy method transferability and cost savings from reduced solvent consumption. The Kinetex 2.6 µm F5 provides performance comparable to sub-2 µm particles on both standard HPLC and UHPLC systems. The 1.7 µm column delivers 20 percent greater efficiencies than fully porous sub-2 µm products.

“Our company truly values the customers’ voice and working beyond the status quo,” explains Simon Lomas, brand manager for Phenomenex. “These new Kinetex F5 columns are the result of years of research, development and customer input. With better, more accurate and higher performance products like the Kinetex core-shell F5, scientists can continue to push the current limits of separation science.

Phenomenex is a global technology leader committed to developing novel analytical chemistry solutions that solve the separation and purification challenges of researchers in industrial, clinical research, government and academic laboratories. From drug discovery and pharmaceutical development to food safety and environmental analysis, Phenomenex chromatography solutions accelerate science and help researchers improve global health and well-being.
