Protein & Peptide Analysis & Purification

HPLC Columns for Every Need

Diazem Peptica products are a complete line of peptide and protein columns designed to give both excellent column performance and selectivity. Diazem proprietary silane bonding chemistry is used to make a wide range of Peptica products for C18, C8, C4, and Phenyl Phases. Peptica products are designed and tested to assure:

  • Good peak shape, even on difficult analytes
  • Good peak shape with low or no TFA
  • High efficiency (80,000 plates/m for 4.6mm I.D. columns)
  • Select Peptica products show high pH stability.
  • Good protein recovery
  • Good lot to lot reproducibility
  • Long column life
  • Alternate selectivity can be achieved for many peptides using Diazem C8 and C18 Peptica columns.

Peptica Performance Challenge


Bovine Serum Albumin presents a challenge to most C18 Peptide and Protein Columns. But compare the distinct peak on the Diazem column to the tailing on the competitor's column.
