  5. SUMIPAX ODS Z-CLUE series


SUMIPAX ODS Z-CLUE has all the properties required as the first selection column for when newly developing an HPLC analysis method.


Supports from method establishment through test analysis, steady analysis, to preparationMaximum column pressure (2 μm column): 60 MPa Supports ultra-high performance LC
The silanol activity is reduced to the extent possible ⇒ Good peak shapes for alkaline compounds and acidic compounds
Acid/alkaline resistance Mobile phase with pH 1-10 can be used
High purity silica gel with little adsorption due to metal impurities is used (metal content is controlled to 1 ppm or less)
Excellent durability and lot reproducibility

Relationships between column pressure and mobile phase composition

Even with smaller particle size (3mm) and longer column (250mm), relatively low column pressure make it possible to use methanol. Even with smaller particle size (3mm) and longer column (250mm), relatively low column pressure make it possible to use methanol.

Deactivation of silanol groups

For SUMIPAX ODS Z-CLUE, residual silanol groups are deactivated as much as possible through endcapping, and alkaline compounds exhibit excellent peak shapes even under a neutral condition where they are susceptible to residual silanol groups the most.

Good reproducibility for column lots

Ultra high performance LC column with particle size 2mm

Fast analysis
