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

Case: Dr Pepper Snapple Group‚ Inc. Grade ID: 12258 Date: 2/14/2011 The problem associated with this case is whether or not the company should introduce a new energy beverage brand into the market. If a profitable market opportunity exists for the company to enter the energy beverage market the next step would be to identify a target market and marketing mix along with a product line and brand positioning. The best opportunity for the company to gain market share is to target adult

INTRODUCTION Extracts from black pepper discourage insect pests from laying eggs on leaves and pose lower risk to humans and the environment than other pesticides‚ a University of Ottawa researcher says. The more susceptible species were pine sawflies‚ which are passed on ornamental plants and caterpillars such as the eastern tent caterpillar Black Pepper worked better when insects are soft-bodied during the larval stage because the chemical is able to penetrate

Most people refer to tongue twisters as fun phrases to say so you’ll... twist your tongue. But the proper definition is... a combination of the same sounds to create a varied alliteration that could put pressure on your tongue which may cause your nerve system go above normal. In other words it can make you go wild

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

Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed

Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).

Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment
