ReproSil 100 C4

Short-Chain Reversed-Phase Column for Peptide and Protein Analysis

ReproSil 100 C4 is a reversed-phase HPLC column from Dr. Maisch HPLC GmbH, packed with ultra-pure, fully porous spherical silica (100 Å pore size) functionalized with butyl ligands. The short alkyl chains provide mild hydrophobic retention, making this phase particularly suitable for peptides, small proteins, and hydrophobic biomolecules where reduced retention compared to C18 or C8 is advantageous. With its balanced retention characteristics and high reproducibility, ReproSil 100 C4 is widely used in bioanalytical workflows, proteomics, and pharmaceutical research for the analysis of biomolecules requiring gentle separation conditions.

ReproSil 100 C4 from Dr. Maisch HPLC GmbH offers reliable and reproducible short-chain reversed-phase performance – the ideal solution for laboratories analyzing peptides and small biomolecules.

Key Features:

  • C4 reversed-phase silica – USP L26

  • 100 Å pore size optimized for peptides and small proteins

  • Mild hydrophobic retention for improved recovery of sensitive analytes

  • High column efficiency and reproducibility

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH

  • Available in 3 µm, 5 µm, and 10 µm particle sizes

Typical Applications:

  • Reversed-phase HPLC of peptides and small proteins

  • Bioanalytical LC-MS of biomolecules with moderate hydrophobicity

  • Proteomics and peptide mapping workflows

  • Method development where C18 or C8 phases are too retentive
