The Kromasil Classic 60 Å family of products is the choice for small, organic molecules when a large, accessible surface area is key for separating peaks in analysis. It also has the added properties of loadability and capacity required for purification.
The well-known Kromasil Classic 100 Å family of products is used to separate and purify molecules of up to about 10 000 Da. In fact, drug candidates for the pharmaceutical, natural products and API industries are separated and purified using Kromasil Classic 100 Å columns and bulk material.
The Kromasil Classic 300 Å family of products is designed to be the perfect choice for proteins and biomolecules larger than 8–10 kDa. This 300 Å material has a narrow pore size distribution that ensures good mass transfer for larger molecules, resulting in narrow peaks and no size-exclusion effects.
The figures below show FE-SEM studies of Kromasil 300 Å, indicating a very regular pore structure, with no voids nor dense clusters.
