J'sphere L80

J'spehere ODS-L80 Semi-Prep Columns from YMC

Alkyl chains of various length, such as C18, C8 and C4, are commonly used for bonding during the synthesis of reversed phase materials to provide different polarity. YMC however, have applied another approach for creating a range of divergent polarities and improving the consistency in the synthesis of reversed phase packings. YMC kept the C18-alkyl chain length constant, but specifically changed content of C18 groups at the silica surface, to produce three different J´sphere ODS packings with graduated hydrophobicity.

J'sphere ODS-L80 has a low polymeric bonded C18 coverage, providing only minor hydrophobic retention. The extremely high H-bonding capacity makes J'sphere ODS-L80 very useful for the separation of polar compounds. Such compounds frequently have molecular sites which are susceptible to H-bonding and hence, are easily separated by a H-bonding mechanism.

J'sphere ODS-L80 is available in 10 and 20 mm ID for semi-prep applications.
