Column and Thin Layer Chromatography

Chromatography was used because of its powerful technique in separating mixtures. In this experiment the Chili pepper pigments was extracted using DCM, the extract was then introduced into the column and eluate was collected, a technique called column Chromatography. Using the Thin Layer Chromatography the purity of the components was tested. The UV lamp was used to spot the UV visible components and the Retention Factor was computed. Keywords: Column Chromatography, Thin-Layer Chromatography, Retention Factor ____________________________________________________________ ________________________________ 1. Introduction Chromatography (color writing) is a separation technique used to identify the components of a mixture and to purify a compound. The mixture dissolves in a solvent, the mobile phase, as it passes through an adsorbent material, the stationary phase. Mikhail Tswett developed this process to separate the pigments in….

Experiment About Properties and Effects of Osmosis

Introduction The reason of this experiment was to identify the properties and effects of osmosis. Osmosis can be defined as the diffusion of water through a selectively permeable membrane. (Miller/Levine) Osmosis occurs when there is an area of higher and lower concentration. Osmosis is a type of diffusion. Diffusion is when molecules move from an area of higher concentration to an area of higher concentration. The three types of concentrations are hypotonic, hypertonic, and isotonic. When in comparison to another solution, a hypertonic solution has a lower concentration, a hypertonic solution has a higher concentration, and an isotonic is when the two solutions have an equal concentration. The experiment tested the relationship between the concentration of an egg and solutions of different concentrations. The hypothesis is that an….

T box

The T- box is a power generated device that harnesses wind energy as trains run over railroad tracks. This alternative form of wind energy produced by trains is very unique, as it does not depend on any natural energy sources. Instead, the energy generated from this device is produced as a consequence of human activity. The T- box device generates energy without any interference of the normal train operation – the device is installed between railroad ties, and is partially buried underground. As the train passes over the device, the wind generated from the train spins the turbine nside the T- box to generate electricity. The T- box contains all the mechanical components required for harnessing, storing and supplying converted power. Hence, the power generated from this device….

Fall of Icarus Poems

After reading Landscape With The Fall of Icarus by William Carlos Williams and Musee Des Beaux Arts by W. H. Auden, a clear idea is present. Both authors seem to minimize the importance of Icarus’s death, but with what intent? In both poems, self-concern outweighs any intentions to help Icarus. It is clear to me what the authors were trying to express by implying that people simply had their own things to do, too used to disaster to even care about anyone besides themselves. In the Landscape With The Fall Of Icarus, Williams makes it clear that people are too concerned with themselves to notice anything happening around them. That idea started to become present when Williams wrote “the edge of the sea concerned with itself”. This quote….
