It is also included below. ?You ar requisite to write a full practical musical paper (1000 words) using the results obtained during the practical. Please read the guidelines at the end of this agendum when writing up. Practical 2 Introduction Separation of compounds on a cu t down layer of supporting sensitive (i.e. TLC or frail layer chromatography) is very speedy and gives good resolution at low concentrations. Separation may be by adsorption, ion exchange, division or jellyatin 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 termination mixture. Method TLC plates Silica gel TLC aluminum sheets will be provided. Handle them cautiously by their edges to hold 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 skip over with clingfilm.Be ware of letting the silica come into encoun! ter with the solvent-saturated paper.
