FAQs on Flash Chromatography

Is flash chromatography the same as HPLC?

Flash chromatography differs from HPLC and UHPLC as it operates at much lower pressures. Flash chromatography is also known as low pressure or medium pressure liquid chromatography. The Flash chromatography operates at pressures of 50 -200 psi, as compared to HPLC, which operates at 1000s of psi, and UHPLC which operates above 10,000 psi.

What is flash chromatography?

Flash chromatography is a variation of normal column chromatography that primarily uses the same material to separate compounds, but operates with a shorter column and higher solvent velocity. Both chromatography methods perform column separation with a different pressure gradient. Flash chromatography is often more economical due to its high speed and more precise control over the solvent flow rate, while normal column chromatography is a more precise method of purification. The more precise nature of normal column chromatography makes it the better choice for most separations, but flash chromatography is still more precise than most other commonly used methods of chemical purification.

What is automated flash chromatography?

Automated flash chromatography is a purification technique that separates compounds by applying a solvent gradient. It is suitable for both small batches and large-scale studies.
