Description
Superspher® improves the separation efficiency of HPLC analysis. This high performance spherical silica carrier with a mean particle size of 4 µm yields an optimum pressure/separation performance ratio, according to both theoretical calculation and practical experience. The number of theoretical plates for Superspher® is > 100, 000 N/. Therefore, these columns are always first choice when complex mixtures demand high peak capacity. A broad range of modifications on Superspher® is available: non-polar derivatives (RP-8, RP-8 endcapped, RP-18, RP-18 endcapped and RP-select B) and polar derivatives (Si 60).
Superspher® packing materials are available as LiChroCART® cartridges in different lengths and different internal diameters (4 mm, 3 mm, and 2 mm). LiChroCART® 3 mm i.d. and 2 mm i.d. narrow bore cartridges for HPLC saves costs by reducing the solvent consumption and allows the handling of very small quantities while increased sensitivity as well as improved resolution are achieved. LiChroCART® cartridges 4 mm i.d., 3 mm i.d. and 2 mm i.d. are compatible to the manuCART® "4" cartridge holder. This facilitates faster and more flexible method adaptation to smaller bore columns.
