Is UHPLC always better than HPLC?

UHPLC offers higher resolution and faster analysis, but it comes with greater cost and stricter requirements—so “better” depends on your specific application.

Can I use the same columns for HPLC and UHPLC?

Typically not. UHPLC columns are optimized for higher pressure and smaller particles, and standard HPLC columns may not perform optimally or safely in UHPLC systems.

What key consumables should I upgrade for UHPLC?

Focus on low-adsorption vials, ultra-clean filters and injection systems with minimal dead volume, to maintain peak shape and reproducibility in UHPLC.
