Lichrosorb is an irregular porous packing material manufactured in Germany by E.Merck of Darmstadt.
Both the bonded and unbonded Lichrosorb Silicas have relatively high surface areas and are considered
as one of the most retentive packing materials
available on the market.
The lichrosorb particles are ground from
coarser precursor materials and classified to
close bands of 5, 7 and 10μm. Pore diameters
of 60 and 100A are available. The 100A
material is available in the following phases:
NH2, CN, Diol, RP-8 and RP-18.
