Answer:It is a 300 × 3.9 mm C18 HPLC column packed with 5 µm silica particles.
Answer:The pore size is 100 Å and the specified pH range is 2–7.5.
Answer:GL Sciences specifies a maximum operating pressure of 20 MPa, equivalent to 200 bar.
GL Sciences Inertsil ODS-3 is a reversed-phase C18 analytical HPLC column packed with 5 µm high-purity silica particles. The 300 × 3.9 mm configuration provides a comparatively long bed for resolving complex mixtures when additional chromatographic efficiency is required. Its octadecyl-bonded, endcapped stationary phase has a nominal 100 Å pore size and a specified pH range of 2–7.5. Inertsil ODS-3 is used in pharmaceutical and chemical analyses involving organic analytes with suitable hydrophobic retention. The column's 3.9 mm internal diameter and 300 mm length affect solvent consumption, run time and pressure compared with shorter 4.6 mm columns. The specified maximum operating pressure is 200 bar, so equipment and method settings must respect that limit.
