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

A Lesson Before Dying Written By Ernest J. Gaines Essay By Alli Francis Lessons are told so others can see the significance of a story or event. They are learned through instruction and support from others and by personal experience. Several characters in Ernest Gaines’ A Lesson Before Dying experienced this‚ particularly Jefferson and Grant. Both men were able to learn from each other and in the end made each other better and more mature people. Grant Wiggins‚ the narrator‚ is the son

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
