Answer:This model is 100 mm long with a 4.6 mm internal diameter.
Answer:It uses 5 µm fully porous C18 silica with nominal 100 Å pores.
Answer:Not automatically. Adjust gradient timing, injection load and flow conditions to the shorter bed and recheck resolution.
The GL Sciences InertSustain C18 HPLC column in the 4.6 × 100 mm format offers a shorter analytical bed for reversed-phase method development and routine separations. Its high-purity silica particles are 5 µm in diameter with nominal 100 Å pores and endcapped octadecyl surface chemistry. The shorter column geometry can shorten run times and reduce mobile-phase consumption when a validated method provides adequate separation of target compounds. Endcapping reduces interaction with residual silica sites and can improve peak shapes for analytes susceptible to surface adsorption. The stated mobile-phase pH range is 1 to 10, with a maximum operating pressure of 20 MPa or 200 bar. When transferring a method from a longer column, adjust flow, gradient timing and injection volume to reflect the new geometry rather than copying conditions unchanged. Use clean, compatible solvents and filtered samples to minimize contamination. The product is a complete analytical column, not a short guard cartridge or an SPE extraction tube.
