Phenomenex added 1.3-micron UHPLC columns to its Kinetex core-shell product line. The 1.3-micron column is the smallest diameter in the Kinetex family and delivers measurably better performance than conventional fully porous media on UHPLC equipment. The Kinetex core-shell family now includes four particle sizes, from 1.3- to 5-micron, providing separation solutions for virtually every chromatographic application and method transferability from UHPLC to HPLC to preparative-scale LC. With efficiency levels over 400,000 plates per meter, the Kinetex 1.3-micron represents a dramatic advancement in LC media technology. While fully porous sub-2-micron columns exhibit significant band broadening due to frictional heating as flow rate increases, the Kinetex particle morphology and packing technology help to reduce these and other effects to ensure high resolution and sensitivity over an extended linear velocity.
