Orpheus WP wide pore Silica based Sorbents for Peptide Purification

Wide-pore (300Å) packing provide the best-reversed phase separations.

• Separation at or near neutral pH produces better resolution than the typical 0.1% TFA acidic mobile phase.
• Peptides of significant size, or rigidity as in the case of a cyclic peptide, will be at least partially excluded from the pores of the 90Å material.
• In addition, narrow pores restrict diffusion. Both effects contribute to peak broadening. Thus, for peptide separations in general, 300Å wide-pore silicas should be the adsorbents of choice.
• Available in Silica, C4, C8, C18, SAX and SCX in format of your choice. Orpheus-WP mixed mode is specially designed for proteomics applications.
