It is also included below. ?You ar needful to write a full practical musical root (1000 words) using the results obtained during the practical. Please read the guidelines at the end of this schedule when writing up. Practical 2 Introduction Separation of compounds on a c ut down layer of supporting mediocre (i.e. TLC or frail layer chromatography) is very fast and gives good resolution at low concentrations. Separation may be by adsorption, ion exchange, division or gelatin filtration depending on the medium employed.

Separated compounds may be detected by methods not possible on constitution, for example with corrosive sprays; in this practical the isolated spy ar visualised nether ultraviolet (UV) light. Here analgesics are separated by adsorption on a contract layer of silica gel using an ethyl ethanoate/ethanol/ethanoic acid outcome mixture. Method TLC plate s Silica gel TLC aluminum sheets will be ! provided. Handle them cautiously by their edges to retain flaking. Preparation of chromatography tank Line small beakers with paper which as it becomes soaked in the outcome produces a stark(a) atmosphere. Add the solvent provided to the beaker to a depth of about 1 cm and secure with clingfilm.Beware of letting the silica come into encounter with the solvent-saturated paper.
