High performance
reversed-phase columns
|
 |
Sumipax ODS A is the first choice of
many chromatographic analyses for
high performance reversed phase
separation.
It has selectivity for a wide range of
organic compounds such as
pharmaceuticals, organic chemicals,
biologicals and natural products.
ODS A is noted for its high efficiency,
selectivity and long lifetimes. |

| Sumipax ODS C series |
- High theoritical plate number
- Fully endcapped
- Excellent peak symmetry
- Ultrapure silica support and high carbon loading
|
|
| Sumipax ODS C provides excellent peak symmetry, even chelating compounds
or basic samples, because ODS C use the ultrapure silica support with a
very low metal content. Sumipax ODS C is a high carbon coverage which exhibits
long retention and high resolution. |

| Sumipax ODS D series |
- High theoritical plate number
- Fully endcapped
- Excellent peak symmetry
- Recommended for analyses of highly polar compounds
- Strong retention in aqueous eluents
|
|
Sumipax ODS D is a unique ODS column with a hydrophobic high carbon loading
and a relatively hydrophilic surface, which is recommended for analyses
of highly polar compounds.
It provides relatively strong retention in highly aqueous eluents even
in more than 95% water. Sumipax ODS D shows different selectivity with
conventional ODS columns. |

The highest level Low Pressure Column in this Field :
Cut the too minute packing material and improvement the method to pack columns
provide the highest level Low Pressure Column. Possible to change 5um column to 3um
column D-210SLP in same conditions even if the Mobile Phase contains Methanol.
Correspondence to High-Through-Put Sumipax ODS-D-210SLP can maintain
the large number of theoretical plates of the Columns whether the Flow-Rate
increases. |

1. High number of theoretical plates but low pressure
( Methanol can be used with 3um particles in 4.6 x 250mm column because
of low pressure. )
2. Extreme inactivation of silanol , Good for basic compound and acidic compound
3. Available pH range : 1 - 10
4. Excellent durability
5. Excellent repeatability |
