Features

1. The effects of metal oxides are suppressed to a minimum due to the use of highly-purified silica gel as a base material in the STR series.
2. STR series columns are durable due to the use of mechanically strong silica gel.
3. STR series columns are highly resistant to acidic and basic mobile phases.
4. STR series columns are easy to operate and display high levels of performance due to low analytical operating pressures.
5. Excellent end capping technology provides sharp peak shapes for basic and acidic compounds, and for samples which form complexes with metals.
6. Coresponds to USP number L01: Octadecyl silane bonded to porous silica or ceramic microparticles, 3 to 10 micrometers in diameter.
7. Column lifetimes have been greatly improved.
8. ULTRON VX-Octyl columns have very low variations between lots and display excellent reproducibility.
9. ULTRON VX-Octyl columns provide shorter analysis times than ODS columns and can also maintain high separation capacities.
10. Volumes of organic solvents can be reduced.
11. Because distribution equilibriums can be achieved quickly and adsorbed materials can be eluted easily in comparison with ODS columns, these columns are perfect for gradient elutions.
