Products: C4

This non-endcapped version of C4 permits separation that is dominated by silanol interactions.

Ideal for purification of erythropoietin (EPO), our C4-P Series is bonded with butyl groups for moderate hydrophobicity.

The low carbon loading of the C4-BIO Series makes it suitable for purification of small peptides, microbial proteins (insulin) and oligonucleotides with wide pH range applications.

Our newest C4 phase, the PK Series is a premium product that has been holistically designed for optimized purification of recombinant peptides with enhanced alkaline durability, mechanical strength, and loadability.

A range of C4 phases with unique carbon loading, chemical resistances, and selectivities are available.
