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.

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