column chromatography उदाहरण वाक्य

Gas chromatography is in principle similar to column chromatography ( as well as other forms of chromatography, such as function of the vapor pressure of the gas.
Resibufogenin can be eluted out with silica gel column chromatography, using a 5 : 1 ratio of cyclohexane to acetone for the solvent in the mobile phase.
In comparison to column chromatography, flows and total solvent usage can in most countercurrent chromatography separations may be reduced by half and even up to a tenth.
By column chromatography on regular silica gel with a hexane / ethyl acetate eluent ( 5 : 1 ), a 66.6 % polar eluent is selected.
Where classical column chromatography uses a solid phase made by a packed bed, EBA uses particles in a fluidized state, ideally expanded by a factor of 2.

Ginkolides "'A-C "'were isolated from a large scale methanolic extraction followed by liquid-liquid partitions, column chromatography and repeated crystallizations.
In this method Merrifield resin is modified as a cyclopentadienyl resin and used as a solid phase against a mobile phase containing the complex mixture in a column chromatography operation.
In 1944 at the ETH, Prelog managed to separate enantiomers with " asymmetric " trivalent nitrogen by column chromatography at a time when this method was still in its infancy.
Column chromatography with a hydrophobic stationary phase such as phenyl-sepharose will cause more hydrophobic proteins to travel more slowly, while less hydrophobic ones elute from the column sooner.
This forms the basis of chiral column chromatography, which can be used on a small scale to allow analysis via Eu ( fod ) 3 and Eu ( hfc ) 3.
