Experiment 9 Thin Layer Chromatography Experiment: 9 Title: Thin Layer Chromatography Introduction: Chemical analysis is conducted on specific analytes (specific substance of interest in a mixture)‚ however it is often found that these analytes must be separated for the chemical analysis to conduct their analysis. Chromatography is a set up of laboratory a technique that is used to separate a chemical mixture. This technique is very useful as it allows us to follow the course of

Ion Exchange Chromatography Week 10 TAG Question 1: Chapter 6-4 of your technique book provides a detailed description of how to run a ion- exchange column. Assume you have a cation-exchange column already prepared and ready to use. Create an outline of no more than 10 steps describing how you will regenerate the column‚ load your sample and collect the hydronium ion released. 1. Open the stopcock at the bottom of the column and allow solution to drain out until the solution level in the

1.5.2.5 Detectors The detectors used in UPLC should be able to handle very fast scanning methods because half-height peak widths of less than one second are usually obtained with columns packed with 1.7 µm particles. The detector must be able to give high sampling rate adequate to capture enough data points across the peak for an accurate and reproducible integration of analyte peak. The dispersion (volume) of the detector flow cell must be minimal to maintain separation efficiency. Conceptually

Yuri Anthony D. Sucgang BMLS-IA Electrophoresis Machine Gel Electrophoresis Apparatus(Aragose Gel) Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson‚ we’ll review how agarose gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment.

Performed on: Wednesday‚ May 8th‚ 2013 | | | 5/15/2013 | | Introduction: The goal of this experiment was to identify an unknown analgesic drug through the use of thin-layer chromatography. The drugs used were‚ Unknown #1‚ caffeine‚ aspirin‚ and acetaminophen. Thin-Layer Chromatography is a technique for identifying substances using a mobile phase (developing solvent) that draws up through a stationary phase (TLC plate) and marks spots of differing distances for differing substances

PAPER AND THIN-LAYER CHROMATOGRAPHY Lab 47 Michael Stravino‚ CHM 2211L‚ June 3‚ 2012 Abstract Thin-Layer Chromatography and Paper Chromatography can be used to identify identical compounds‚ unknown compounds‚ the number of components in a mixture‚ as well as other important uses not explored in this laboratory. This experiment explores these techniques to identify an unknown amino acid by TLC and analyze food colors using paper chromatography. By using 2.0 mL of dimethoxyethane and 18 mL of

Experiment # 4 Paper Chromatography 1. Why is the chromatogram developed in an essentially closed system? - The chromatogram is developed in a closed system in order to prevent the solvent to evaporate. Most solvents used in the chromatograph are toxic and flammable. It is also put in a close system to reduce the chance of outside factors affect the chromatograph. 2. What is the main advantage of 2-dimensional paper chromatography over a 1-dimensional one? - The
