Separation Techniques

Efficient separation techniques are key for competitive natural product chemistry, nowadays. Available technologies range from high-throughput separation for quantitative analysis of target molecules at femto- or picogram levels all the way up to the gram-scale preparative isolation of bioactive molecules from nature’s complex compound mixtures such as, e.g. food and botanical extracts, plasma, saliva, and urine.

Ultraperformance liquid chromatography (UPLC)

High-performance liquid chromatography (HPLC)


2-Dimensional high-performance liquid chromatography (2D-HPLC)

High-performance ion chromatography (HPIC) with pulsed amperometric detector (PAD) or  conductivity detector with electrochemical suppression (sCD)

semipreparative to preparative separations

ultrafiltration (stirred cell, gas pressure filtration, tangential flow filtration)

gel permeation chromatography (GPC)

automated flash chromatography (AFC)

High-performance liquid chromatography (HPLC)

2-Dimensional high performance chromatography (2D-HPLC)
