Answer:3.9 mm internal diameter × 300 mm length, with 10 µm particles and 125 Å pores.
Answer:Silica-based C18 reversed-phase packing with irregular particles.
Answer:pH 2–8.
The Waters µBondapak C18 analytical HPLC column uses a traditional silica-based octadecyl-bonded reversed-phase stationary phase. Its irregular 10 µm particles with 125 Å pores are packed into a 3.9 mm inner diameter by 300 mm length format. The bonded chemistry provides a characteristic balance of hydrophobic retention and silanol activity that can be important for established analytical methods and method transfer. The column is endcapped and supports operation over the listed pH range of 2–8. The 300 mm column length makes this format distinct from shorter C18 columns used for rapid screening.
