Effortless high-performance purification

3 Mar 2026

Chromatography plays a central role in achieving reliable separations, enabling scientists to isolate, purify, and analyze complex mixtures with confidence. As workflows become more demanding, laboratories increasingly rely on systems that combine ease of use, high‑quality separations, and robust safety features to deliver consistent, reproducible results.

The Pure Excellence line from BÜCHI delivers intuitive purification with user‑focused features such as streamlined software, a one‑hand quick‑release cartridge holder, and automated sample injection to reduce errors. Explore the Pure Excellence range including the C‑905, C‑910, C‑915, and C‑950 systems that offer versatile flash and prep HPLC solutions for diverse workflows.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Flash chromatography systems use small silica gel particles for separation and a pressurized gas for driving the solvent through the column or pre-packed cartridge.
