ReproSil DIBS-C4

Modified C4-Phase for Direct Injection of Biological Samples

ReproSil DIBS-C4 is a silica-based HPLC column with a butyl bonded phase developed for the Direct Injection of Biological Samples (DIBS). The C4 modification provides moderate hydrophobic retention, making it particularly well-suited for the separation of proteins, peptides, and other biomolecules from complex biological matrices. The specialized DIBS surface chemistry minimizes secondary interactions and adsorption of biomolecules, allowing reliable direct injection of plasma, serum, or other biological fluids without extensive sample preparation. With its robust silica backbone and optimized surface properties, ReproSil DIBS-C4 ensures reproducible results, sharp peak shapes, and long column lifetimes.

ReproSil DIBS-C4 combines the robustness of silica with tailored C4 modification – the reliable solution for reproducible and efficient direct injection bioanalysis.
