imChem proposes this range of fine products:
The performance of Coral packings comes from the high quality and purity of our silica (99.95%) and extremely low metal content
– less than 10 ppm in total.
Coral silica particles are spherical and exhibits a uniform surface and extremely narrow size distribution. Strict quality control guarantees consistent pore sizes and pore structure, enabling high mechanical strength and enhanced bed stability.
Those characteristics results in reproducible packing batch to batch, column to column, either analytical as preparative, allowing longer column lifetime.
With a specific surface area of 310 m2/g and 100Å pore diameter, Coral was developed to display a high load capacity and deal with small to medium molecules (up to 7,000 Da), which is ideal for both analytical and preparative work.
