A research group from the Mendel University of Agriculture and Forestry (Brno, Czech Republic) and the Academy of Sciences of the Czech Republic (Trebon, Czech Republic) combined solid-phase exraction (SPE) and supercritical fluid extraction (SFE) using an SPE cartridge incorporated in an SFE cell to extract benzoic acid and cinnamic acid derivatives from microalgae and cyanobacteria samples.
A research group from the Mendel University of Agriculture and Forestry (Brno, Czech Republic) and the Academy of Sciences of the Czech Republic (Trebon, Czech Republic) combined solid-phase exraction (SPE) and supercritical fluid extraction (SFE) using an SPE cartridge incorporated in an SFE cell to extract benzoic acid and cinnamic acid derivatives from microalgae and cyanobacteria samples. The compounds were further analyzed and identified by high performance liquid chromatography (HPLC) with electrospray mass spectrometry. The researchers found that the technique could be useful for analyzing various plant species for trace amounts of phenol compounds.
HPLC 2025 Preview: Functionalized Monoliths as Selective Sample Preparation Materials
May 16th 2025Analyzing trace compounds from complex samples often requires purification and pre-concentration, and online coupling of solid-phase extraction (SPE) with liquid chromatography (LC) helps minimize analysis time and solvent/sample use. Monoliths with large macropores are ideal for this coupling due to their low back pressure and versatility in various formats.
