ReproSil DIBS-C8 is a high-purity silica-based HPLC column featuring an octyl bonded phase designed for the Direct Injection of Biological Samples (DIBS). The medium-chain C8 modification provides a balanced hydrophobic retention that is ideal for peptides, proteins, and metabolites in complex biological matrices. The DIBS-specific surface treatment reduces non-specific adsorption and suppresses unwanted matrix effects, enabling reliable direct injection of serum, plasma, and other biological fluids. With its robust silica support and optimized bonding chemistry, ReproSil DIBS-C8 ensures consistent performance, sharp peak shapes, and excellent reproducibility across demanding bioanalytical applications.
ReproSil DIBS-C8 combines medium hydrophobic selectivity with DIBS technology – the dependable choice for direct bioanalysis of complex samples.
