DAISOGEL SP-P Series
image
  • Ultra high purity silica
  • Narrow particle size distribution
  • Higher loading capacity
  • Enhanced mechanical stability

DAISOGEL SP-P (spherical ultra pure) series are based on spherical and totally porous silica gel with metal impurities specified to be less than 10 ppm each for Al, Fe, Ti and Zr. Its manufacturing process under strictly controlled conditions produces a material with reproducible distribution of particle and pore size and surface area. The presence of performance-degrading small pores is avoided.
DAISOGEL SP-P series packing materials for analytical applications are available in 3um, 4um and 5um.
Nowadays, preparative liquid chromatography is used for the purification of a wide range of high value products.
DAISOGEL SP-P series packing materials for preparative chromatography feature narrow particle size distribution and ultra high silica purity. Using DAISOGEL, scale up is guaranteed by a using the same production procedure for all grades.
DAISOGEL SP-P series packing materials for preparative use are available in 7um, 10um, 15um and 20um.
High purity 40-60um spherical silica is a cost effective alternative for medium and low pressure chromatography.

fig

DAISOGEL‘s pore structure features the absence of performance-degrading micro pores which are not accessible by solute molecules and maximum surface area.
This leads to higher resolution for analytical applications and higher loading capacity for preparative applications.

fig

Preparative grades packing material in the past have had a wide particle distribution. The advantage of DAISOGEL SP-P series packing material for preparative chromatography enables higher column efficiencies and lower operating pressure due to its narrow particle size distribution.

fig

DAISOGEL SP-P packing‘s narrow particle size distribution provides better flow characteristics, improved column efficiency and longer column life.
