Flash Chemistries/Media
Claricep CM utilizes silica that is further purified with a proprietary acid washing process which results in even lower surface activity to result in an improved peak shape and resolution.
Consistent High Performance: High loading capacity (high surface area > 350m2/g) combined with good resolution for tight band definition (no tailing)
Wide Range of Selectivities: Variety of sorbents to meet any separation needs -(Silica (Si), C18, C8, AQ C18, Phenyl, Cyano (CN), Diol (OH), Amino (NH2) and HILIC (Urea) along with a large variety of cartridge sizes from 4 g to several kilograms allows for purification scale-up from milligrams to kilograms
High Pressure Tolerance: Exceptional durability to withstand high pressures due to closed-top spin-welded technology on standard hardware sizes that allows for pressure up to 12 bar (180 PSI)
Excellent Hardware: Universal luer fittings for compatibility with any flash system for great compound purity & recovery and 100% guaranteed leak-free.
High Quality: Consistent homogeneous packing allows for no channeling and creates reproducible high plate count (N).

HPLC TEST
Unmodified and Deactivated Silica were packed into individual
stainless steel columns (4.6 x 150 mm) and then evaluated on a
HPLC System |
Irregular Silica Comparison
Ultra pure packing which results in much less abnormal surface activity. This produces chromatograms with much sharper peaks

Spherical Silica Comparison
Regular, similar-sized and high quality particles can be packed in a column much more uniformly which reduces eddy flow currents and lateral diffusion. The result is greater peak symmetry and baseline resolution than is possible with irregular silica particles.
