Chromatographic Separation of Sodium Fluorescein and Methylene Blue In this two-part lab the students will: • Learn the techniques associated with thin layer and column chromatography. • Determine the effects of the stationary phase in separating a mixture by chromatography. • Determine the effects of the mobile phase in separating a mixture by chromatography. • Conduct a separation using column chromatography. In the first week‚ the students will determine the best solvent system for

Impacts of solid waste on health The group at risk from the unscientific disposal of solid waste include – the population in areas where there is no proper waste disposal method‚ especially the pre-school children; waste workers; and workers in facilities producing toxic and infectious material. Other high-risk group include population living close to a waste dump and those‚ whose water supply has become contaminated either due to waste dumping or leakage from landfill sites. Uncollected solid waste

Genevieve Sierra Chemistry seg. 2 June 15‚ 2014 05.05 mixtures and solutions: Lab report: outline Ink chromatography Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. It is used to separate substances. Examples of chromatography are finger-printing‚ medicines‚ and separating/ testing histamines. http://www.biotecharticles.com/Agriculture-Article/Applications-of-Chromatography-1299

BASIC SEPARATION TECHNIQUES Contemporary modifications of filtration and dialysis use a matrix-based fibrous material that provides a mechanism of separation in many homogeneous immunoassays. These materials may be coated with specific antibody-ligand to foster selection of specific materials or species. Certain labels use magnetic particles in conjunction with strong magnets to effect separation. Basic universally used separation mechanisms‚ outside of those incorporated in immunoassay‚
