Phenomenex has announced the addition of two new phases in its Kinetex core-shell HPLC/UHPLC column family.
Kinetex XB-C18 and Kinetex C8 are said to bring the advantages of ultra-high performance liquid chromatography (UHPLC) within standard HPLC operating pressures to a growing list of applications.
The company said the Kinetex core-shell technology meets researchers' needs to improve results and increase productivity without large capital expenditures.
The Kinetex XB-C18 is claimed to provide a unique 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 Kinetex phase has produced differences in peak elution order and improved separation of co-eluting compounds.
The Kinetex C8 phase meets the US Pharmacopeia specifications for Classification Code L7, enabling laboratories using L7 columns to realise the benefits of Kinetex core-shell technology while staying compliant with USP-allowable adjustments.
The new Kinetex core-shell columns are available in two particle sizes - 2.6- and 1.7- micron - and in variety of column dimensions.
