Kromasil diC4 from Nouryon consists of fully porous particles with a dibutylsilane modification. The material is available both in bulk and in pre-packed columns. The pore size of this material is 100 or 300Å and has a particle size of 10 to 16µm.
Phase | Pore size | Particle size |
Kromasil 100 diC4 | 100 Å | 10, 13 µm |
Kromasil 300 diC4 | 300 Å | 10, 16 µm |
Conclusion: Kromasil diC4 offers steric selectivity between C18 and C4 and can therefore lead to a higher yield.
