Superspher® HPLC columns
High Efficiency and High Peak Capacity HPLC of Complex Mixtures |
Request Information |
Superspher® columns are specially designed for highly efficient HPLC separations. According to both theoretical calculation and practical experience, these high performance spherical silica carriers, with a mean particle size of 4 μm, provide an optimum pressure to separation performance ratio. The number of theoretical plates for Superspher® HPLC columns is > 100,000 N/. This makes them the ideal choice for complex sample mixtures that require high peak capacity.
Features and Benefits
- Highly efficient HPLC separations
- Optimum pressure to separation performance ratio
- Number of theoretical plates > 100,000 N/
- Ideal for complex mixtures requiring high peak capacity
Packing Materials
Superspher® packing materials are available as LiChroCART® cartridges with a variety of lengths and internal diameters (4 mm, 3 mm, and 2 mm). LiChroCART® 3 mm i.d. and 2 mm i.d. narrow bore cartridges for HPLC reduced solvent consumption while increasing sensitivity and resolution. Hence, they save costs and efforts involved with handling large solvent quantities. LiChroCART® 4 mm i.d., 3 mm i.d. and 2 mm i.d. are compatible with the manu-CART® “4” cartridge holder. This enables faster and more flexible method adaptation to smaller bore columns.
