It is also included below. ?You ar compulsory to write a full practical musical formation (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 sup porting median(a) (i.e. TLC or frail layer chromatography) is very rapid and gives good resolution at low concentrations. Separation whitethorn 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 under(a) ultraviolet (UV) light. Here analgesics are separated by adsorption on a contract layer of silica gel using an ethyl ethanoate/ethanol/ethanoic acid firmness of purpose mixture. Method TLC plates Silica gel TLC alumi! num sheets will be provided. Handle them cautiously by their edges to interdict 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 loom with clingfilm.Beware of letting the silica come into encounter with the solvent-saturated paper.
