J'sphere M80

J'sphere ODS-M80 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.

The lower coverage of C18 monomeric bonded groups in J'sphere ODS-M80 provides moderate hydrophobicity. As the lipophilic character is decreased, the H-bonding capacity becones more and more important. J'sphere ODS-M80 has a pronounced balanced polarity which is extraordinary flexible and allows application to a wide variety of separation problems. Depending on the separation J'sphere ODS-M80 columns can be operated over a very broad range of eluent polarity. J'sphere ODS-M80 columns are a very adaptable tool in various fields in analytical HPLC including drug analysis and QC.

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