Answer:50 mm long with a 4.6 mm internal diameter.
Answer:2 µm silica particles with 120 Å pores.
Answer:Reversed-phase chromatography with a C18 bonded stationary phase.
The YMC-UltraHT Pro C18 column provides high-efficiency reversed-phase separation in a short, 50 × 4.6 mm format packed with 2 µm particles. Its C18-bonded, 120 Å silica phase supports chromatographic retention of moderately hydrophobic molecules, including pharmaceutical compounds and other small organic analytes. The short bed enables rapid gradients and compact method development while the fine particle size can improve separation efficiency compared with larger-particle columns. A 4.6 mm internal diameter accommodates conventional analytical liquid chromatography flow configurations when pressure capacity is sufficient for the 2 µm packing. Method development should balance organic solvent composition, temperature, flow rate and sample solvent to achieve practical resolution without exceeding the column or instrument pressure limits. Filter samples and mobile phases to reduce particulate loading and protect the inlet frit. Use a compatible guard where the matrix contains strongly retained contaminants. This is a complete prepacked analytical HPLC column, not loose C18 stationary phase or a guard cartridge.
