A separation model of ionizable and neutral enantiomers with cyclodextrin-sodium dodecyl sulphate (SDS) micellar electrokinetic chromatography was established.
Methods A combination of euglobulin precipitation, ion-exchange chromatography,(NH4)2SO4 precipitation and affinity chromatography was used in the process of purification.
Tetrachloroethane in air was collected by activated carbon,desorped with carbon disulfide,separated by GDX-103 chromatography column,and detected by flame ionization detector.
The soybean phosphatidylethanolamine and phosphatidylinositol were prepared by combining methods of solvents extraction and silica gel column chromatography from soybean oil sediment.
METHOD Qualitative test with thin-layer chromatography was performed on Yunkeping Granule, with Spica Prunellae Vulgaris, Herba Plantaginis and urson as the control.
He used gas chromatography, coupled with human sniffing, to identify about three dozen aromatic compounds contributing to the whiskey's flavor profile.
Intrigued by that discovery, the team put the crude sample they were working on through two rounds of chromatography, to split it into its constituents, and repeated the tests on these.
