- SUPERIOREXII ODS
A novel high-carbon column released with excellent high loading capacity, and outstanding lot reproducibility.
SUPERIOREX II ODS is a successor model of SUPERIOREX ODS, with not only the same feature of high carbon product, but the greatly improved durability, and lot-to-lot variation. This column has also the high loading capacity, and it is suitable for semi-preparative chromatography. It can be used for general purposes C18 column such as an analysis of isomer with inadequate separation, or retention.
Features
High-carbon (25%) shows high retention power.
→SUPERIOREX II ODS has the most hydrophobicity column in the Osaka Soda columns line-up.
HPLC ideal media for the semi-preparative chromatography due to the high loading capacity
→SUPERIOREX II ODS has an excellent high loading capacity compared to CAPCELL PAK series, or SUPERIOREX ODS, and it is an ideal, and a suitable column for semi-preparative chromatography.
Outstanding lot reproducibility
→SUPERIOREX II ODS has an outstanding lot reproducibility with the retention time, and the peak shape. It can be also used for the routine analysis such as reliable quality control.
Separation of isomer
SUPERIOREX II ODS has the feature of a high carbon column, and it has an excellent performance with high steric selectivity. The example analysis of three kinds of isomer: ortho (o-), meta (m-), and para (p-) Terphenyl which have aromatic hydrocarbons is shown.
