Answer:The column is 3.0 mm ID × 125 mm long.
Answer:The column uses 5 µm particles.
Answer:The column uses a base-deactivated C18 reversed-phase stationary phase.
Hypersil™ BDS C18 is a general-purpose base-deactivated reversed-phase column designed for reliable HPLC analysis across many routine applications. This configuration uses 5 µm particles in a 3.0 × 125 mm analytical column. The BDS surface treatment reduces unwanted interaction with residual silanols and supports improved peak symmetry for basic compounds while retaining conventional C18 hydrophobic selectivity. The stationary phase has approximately 130 Å pores and a stated operating pH range of about 2–8. The 125 mm length offers a balance between resolution and analysis time, making it useful for pharmaceutical QC, assay methods, impurity profiling, food analysis, and other established reversed-phase procedures.
