Kromasil Classic 300A

 

Kromasil 300A phases are manufactured to exhibit a surface chemistry similar to the well-established Kromasil 100A phases. This ensures excellent peak shape and resolution for acidic, neutral and basic molecules. Kromasil 300A phases are designed for the analysis of proteins and small biomolecules (larger than 8–10 kDa). A narrow pore size distribution ensures good mass transfer for molecules in this range, resulting in narrow peaks and no size exclusion effects.

Kromasil 300A silica phases offer high mechanical strength, an important consideration for larger columns. They also offer good chemical stability. Columns from analytical to preparative scale (up to 50mm i.d.) and bulk materials are available.

  

The general features of Kromasil Classic 300A phases include:

  • 300A spherical silica
  • High mechanical and chemical stability
  • SIL, C4, C8 and C18 phases
