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