Column Line

Phenomenex announced the addition of two new phases in its Kinetex core-shell HPLC/UHPLC column family. Kinetex XB-C18 and Kinetex C8 bring the advantages of ultra-high liquid chromatography performance (UHPLC) within standard HPLC operating pressures to a growing list of applications. The technology meets researchers’ need to improve results and increase productivity without large capital expenditures.

XB-C18 provides a high degree of selectivity, incorporating two iso-butyl side chains at the base of the C18 ligand to reduce secondary interactions with residual silanols. These columns deliver enhanced separation and peak shape of basic compounds under neutral and acidic pH conditions. In comparison studies with other C18 columns, this new phase has produced differences in peak elution order and improved separation of co-eluting compounds. C8 phase meets the United States Pharmacopeia (USP) specifications for Classification Code L7, enabling laboratories using L7 columns to realize the benefits of the technology while staying compliant with USP-allowable adjustments.
