New Particle Sizes for Chromatography Columns

Phenomenex Inc., a global leader in the research and manufacture of advanced technologies for the separation sciences, introduces 2.6µm and 1.7µm EVO C18 particle sizes, expanding the company’s Kinetex core-shell column family. The columns provide a unique C18 selectivity offering excellent peak shape for bases, 100 percent aqueous stability and rugged pH stabilityfrom 1 to 12 by incorporating a patented organo-silica grafting process that utilizes uniform stabilizing ethane cross-linking. Kinetex EVO C18 delivers the performance advantages of Core-Shell Technology at low, neutral and high pH ranges, making it an excellent addition to any lab’s current reversed phase column portfolio. The new, smaller particle sizes extend the versatility and scalability of this media, which was introduced initially in 5µm particles for HPLC and preparative HPLC work. Overall, the columns are suitable for virtually every industry that relies on chromatography, including pharmaceutical drug discovery and development, clinical research, forensic toxicology, food safety and quality and environmental analysis.

The rugged columns are an extension of the Phenomenex Kinetex core-shell line, which delivers improved results, increased productivity, easy transferability and significant cost savings compared to traditional HPLC/UHPLC media. The new 2.6µm EVO C18 columns offer performance comparable to sub-2µm fully porous particles on both standard LC and UHPLC systems, but at lower backpressures. The new 1.7µm particle size is designed for use with UHPLC systems and delivers on average 20 percent greater efficiencies than fully porous media. Both of these new particle sizes are directly scalable to each other and to the existing 5µm size, making method transfer between UHPLC, HPLC and preparative HPLC techniques straightforward.
