FAQs

Question: Why is the aQ C18 phase useful for polar analytes?

Answer:Its polar endcapping improves retention and peak shape for polar compounds and allows use with highly aqueous or 100% aqueous mobile phases.

Question: What particle technology is used?

Answer:The column uses 2.6 µm solid-core silica particles for high efficiency with lower backpressure than typical sub-2 µm particles.

Question: What are the dimensions of this column?

Answer:The analytical column is 150 mm long with a 4.6 mm internal diameter.

Application Note

Accucore™ aQ C18 Polar Endcapped HPLC Column, 150 x 4.6 mm, 2.6 µm is used for reversed-phase separation of polar and moderately hydrophobic compounds, especially methods that require highly aqueous mobile phases. The stationary phase combines C18 bonding with polar endcapping, allowing operation in 100% aqueous mobile phase without the phase-collapse behavior that can limit conventional C18 materials. Its 2.6 µm solid-core silica particles reduce band broadening and provide high efficiency while keeping backpressure lower than typical sub-2 µm UHPLC particles. The 150 mm × 4.6 mm format can be used on conventional HPLC or UHPLC platforms where longer column length and standard analytical diameter are preferred. The packing has an 80 Å pore size, 130 m²/g surface area and 9% carbon load. The column supports pH 2–9, temperatures up to 70°C and pressures up to 1000 bar.
