Procedure for making a chromatographic columnChromatography column consists of a cylinder swept by a piston. The novelty is that (a) part of the cylinder chamber contains the packing (33), while the other part of the chamber on the other side of the piston and holding the piston rod, is ...
The pressure is applied and the mobile phase moves the analyte through the column. The separation is accomplished using a column coated with a stationary phase. Image Source:Bitesize Bio.

and Bassrah (from Iraq) was successfully carried out using a new approach coded NAASAR, (n-alkanes, asphaltenes, aromatics and resins) comprising urea adduction followed by gas chromatographic analyses (for n-alkanes), n-heptane precipitation (for asphaltenes) and column chromatography (for resins...
E) protect the compound with unprotected agent to obtain a mixture of pharmaceutical compound (IX) isotopes;This reaction is mainly manifested in the aspects of alcohol solvent, tetrahydrofuran, etc.; and (f) the separation of an isomer from a compound by column chromatography to obtain gemstones...
A simple procedure, involving low pressure column chromatography, for purification of the cytokinin bases in treated extracts, and a scintillation proximity immunoassay for their quantification, were developed. The total level of each cytokinin base [N 6 -(2-isopentenyl)adenine, zeatin and dihydro...
COLUMN LIQUID CHROMATOGRAPHYCOLUMN PACKINGSSILICA GELPOROUS CARBONThe analytical data from an initial validation of a new method developed for determining aromatics in distillate fuels is reported. The method applies supercritical fluid chromatography (SFC) for the liquid chromatographic separation of total ...
