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

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

Industrialization with the aid of science has polluted air‚ water‚ food and the atmosphere. The ozone layer is giving threatening signals. So here is a case for man to consider science as a cause of ruin. The aim of science is search for truth‚ and to know things‚ hitherto unknown.

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

1. Physical Layer. Is the physical connection between the sender and the receiver. It includes all the hardware devices (computers‚ modems‚ and hubs) and physical media (cables and satellites). This layer specifies the type of connection and the electrical signals‚ radio waves‚ or light pulses that pass through it. 2. Data Link Layer. Is responsible for moving a message from one computer to the next computer in the network path from the sender to the receiver. This layer has 3 functions: a

Ozone depletion‚ climate change as well as the direct effects of chemicals from industrial emissions and fuel combustion are a great threat to our planet and if nothing is done to resolve this problem soon‚ the results may be disastrous. There is a layer of chemicals twenty kilometers up in the stratosphere called the ozone layer. This layer protects the inhabitants of earth by reflecting much of the suns harmful ultra violet (UV) rays. Without this layer above us‚ many living

Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities

Chloroflourocarbons (CFCs)‚ are chemical agents commonly found in refrigerants‚ aerosol sprays‚ and in the manufacturing of Styrofoam and industrial solvents. With the rate of more than a half-million tons of CFCs being spewed into the atmosphere yearly‚ the rate of ozone depletion is rising at an alarming rate.
