Eiroshell™ Core Shell Silica
Glantreo synthesise silica. We identified a gap in the market, monodispersed silica without classification.
1. Highly monodispersed without the need to size classify leading to high chromatographic efficiency
2. Monodensity leading to higher packing stability as there are no macro pores within the particles.
3. ‘Hard Silica’ (produced with heat during manufacturing) leads to greater stability and longevity of material and columns.
The foundation of any good chromatography column is the stationary phase. We are experts in stationary phases.
Eiroshell™ is a patent protected product range of highly monodisperse, durable and reproducible porous core-shell silica particles manufactured by Glantreo. Our proprietary process is completely tuneable allowing control over physical properties of the particles including the core and shell dimensions. The technology uses a sol gel templating approach to grow a porous silica layer on the solid silica core.
Whilst the Eiroshell particles have a standard pore size of 100A, we have also augmented the Eiroshell process with our core enlargement technologies to produce a range of pore sizes from 100A to 1000A. These particles have been commercialised in our Eiroshell™ RP and Eiroshell™ Bio Columns.
If you have a custom particle requirement then ‘Ask and Expert’ and we can discuss in more detail.
