Solved in 2 steps
- What mode of chromatographic separation (RPLC, NPLC, HILIC, SEC, IEX) is best used for the Separation of uric acids and position isomers of dimethyl uric acids in the urine? What stationary phase and mobile phase (together with elution technique), and other chromatographic conditions needed?6) You are given a mixture of organic compounds suspected of containing various amines (e. g. 4-chloroaniline). What is the best way to quickly separate these amines from the other organic compounds? a) Perform a fractional distillation on the mixture. b) Benchtop silica gel column chromatography. c) Dissolve the mixture in an organic solvent and treat the solution with aqueous HCI. d) Dissolve the mixture in an organic solvent and treat the solution with aqueous NaOH.The compounds biphenyl and naphthalene are presented in a mixture. Can hexane be used as a solvent to separate the compounds by column chromatography with silica gel as the stationary phase? Why or why not.
