Features

Uniformly spherical particles

High chemical purity

The impurities which most affect silica are the metal ions content, due to they cause the non-desired analyte adsorption to the chromatographic support

The ULTRABASE® silica has high chemical purity; its metal ion content of Fe, Zr, Al and Ti is <10 ppm

Optimum porosity

During the chromatography process the analyte separation depends on the contact with the silica surface particle, it is essential to the silica porosity thus this porosity is an important parameter to define the silica quality

ULTRABASE® silica fulfil with these requirements

High specific surface

Due to its bigger area of specific surface presents higher retention in the separation of elements thus a better resolution

High particle size distribution uniformity

Its extremely narrow particle distribution, the pore size of 110 as well as the high area of specific surface allows higher peaks retention, higher load capacity and a better resolution

3 and 5 Î¼m used particle sizes are suitable to fulfil the chromatographic needs from analytical to high speed
