DiamonBond™-C18 Columns



Zirconia or zirconium dioxide (Zr02) is a metal oxide that exists in a variety of crystalline and amorphic forms. The chief advantage of Zirconia in comparison with the traditional silica base packings is its unique and specific selectivity as well as outstanding thermal stability and chemical resistance.
In contrast to silica, Zirconium is totally stable within the complete pH range (0-14) and allows operation at temperatures as high as 200°C.
With respect to the polymeric packings on the market, Zirconia has an advantage in its exceptional mechanical resistance, and in not having the problems of incompatibility with certain organic solvents as is the case with the polymeric packings.
Available in a variety of particle sizes, between 3 and 20 μm, the operation of separations from ultrarapid to semi preparative is possible.

• Superior selectivity and better chromatographic peaks in the separation of basic compounds.
• Easy transfer of methods from conventional ODS columns.
• Stable between pHs of 1 to 14.
• Excellent thermal stability for rapid separations.
• High efficiency (> 120,000 plates/metre.)

DiamonBond™ -C18

DiamondBond™ -CI8
• Excellent selectivity for acidic compounds.
• pH stable between 1 and 14
• Excellent thermal stability for rapid analyses.
This packing contains CI8 groups co-valently bonded to the carbon coated surface of the Zirconia. The extreme strength of the carbon-carbon bonds practically eliminates any bleeding of the column whatever, improving derived from the base line, preventing falls in retention times and bettering the sensitivity in all LC/MS applications.
