It is also included below. ?You ar needful to write a full practical musical radical (1000 words) using the results obtained during the practical. Please read the guidelines at the end of this docket when writing up. Practical 2 Introduction Separation of compounds on a cut down layer of supporting metier (i.e. TLC or frail layer chromatography) is very speedy and gives good resolution at low concentrations. Separation may be by surface assimilation, ion exchange, division or changeatin 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 down the stairs ultraviolet (UV) light. Here analgesics are separated by adsorption on a contract layer of silica gel using an ethyl ethanoate/ethanol/ethanoic acid re upshot mixture. Method TLC plates Silica gel TLC aluminum sheets will be provided. ! Handle them cautiously by their edges to forestall flaking. Preparation of chromatography tank Line small beakers with paper which as it becomes soaked in the solvent produces a stark(a) atmosphere. Add the solvent provided to the beaker to a depth of about 1 cm and lodge over with clingfilm.Beware of letting the silica come into encounter with the solvent-saturated paper.
