COSMOSIL CNT
Specialty for Fullerenes / Separation of Soluble Carbon Nanotubes
COSMOSIL CNT series are ideal for separation of soluble carbon nanotubes based on sizes. COSMOSIL CNT series are packed with hydrophilic group-bonded silica packing material. The columns are specially designed to avoid adsorption of carbon nanotubes to silica support and thus ensure high resolution and maximum recovery of carbon nanatubes. COSMOSIL CNT series are available in three different pore sizes, 300 Å, 1000 Å and 2000 Å, respectively.
Features
- Size-based separation of soluble carbon nanotubes
- Hydrophilic group coating silica packing material
- Three types of pore sizes (300 Å, 1000 Å, 2000 Å)
- High durability
