(physical chemistry) A device used in radial chromatography in which solvent is added to the center of a covered silica layered plate which spins to drive a sample outward forming sample spots of different compounds as concentric rings..
Column chromatography SiO₂, 70–230 and 230–400 mesh and disc chromatography with a chromatotron (2 mm thickness, SiO₂ plate) were adopted.
Column chromatographic separations were performed on silica gel 60 (0.04–0.063 mm, Merck, Darmstadt, Germany), a pre-packed silica gel column (35 mm i.d. × 600 mm, Merck, Darmstadt, Germany), and chromatotron (silica gel 60, 0.04–0.06 mm, 1 mm, Merck, Darmstadt, Germany).
Sub-fraction F2.2 was purified using a chromatotron eluting with 35% EtOAc-n-hexane to give compounds 5 (57.9 mg) and 6 (30.1 mg). Sub-fraction F2.3 was further separated by chromatotron (using 40% EtOAc-n-hexane, as eluent) to give compounds 7 (42.0 mg) and 8 (11.3 mg).
Use chromatotron when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
