The Latest Technological Teaching Aids Today’s generation of school children are part of a “connected” age where it is natural to not only use technology in everyday life‚ but in school as well. New technologies in the classroom offer a more engaging way to learn‚ one where the students no longer learn passively but instead by interacting‚ with computers and electronic devices the new school supplies. University level‚ high school and primary students alike are beginning to make good use of fast-moving

Thin Layer Chromatography Introduction Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography‚ but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase and a mobile phase. In the case of TLC the stationary phase is the silica gel on the TLC tray. Procedure Chromatograph method is a method of separating mixtures of two or more compounds. Two phases

The first case of HIV was diagnosed in 1968. Within the next three decades it became the leading cause of death for adults 25 to 44 years old. AIDS is the final stage of HIV (human immunodeficiency virus) ‚ a virus that ravages the immune system leaving the body susceptible to multiple infections. In the public’s mind HIV/AIDS was a disease that belonged to intravenous drug users‚ homosexuals‚ and others in an unfortunate and stigmatized group.

Separations: Chromatography of M&M and Ink Dyes Almost all substances we come into contact with on a daily basis are impure; that is‚ they are mixtures. Similarly‚ compounds synthesized in the chemical laboratory are rarely produced pure. As a result‚ a major focus of research in chemistry is designing methods of separating and identifying components of mixtures. Many separation methods rely on physical differences between the components of a mixture. For example‚ filtration takes advantage of substances

Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf. Introduction: (i) General Concepts Chromatography is a common and powerful method used to separate and analyze complex

Column and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on
