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

Analgesic’s Active Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance

along the stationary phase with the mobile phase until such time that the sample is dissolved. Chromatography is divided into several types. Column Chromatography uses a powder adsorbent placed in a vertical glass column as its stationary phase and its solvent as the mobile phase. The mixture is distributed as the solvent moves down the column. Thin Layer Chromatography‚ or TLC‚ also uses a powder absorbent which is fixed to a metal‚ plastic or glass plate as its stationary phase. The mixture to

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used to determine

Experiment 10 Thin Layer Chromatography Purpose! To identify how many components are in a mixture and the identity of a compound in a mixture by comparing the Rf of a known compound with the Rf of an unknown compound. Intodection. In this experiment the thin-layer chromatography the (TLC) will be used to determine the composition of various over-the-counter analgesic. We will be given two commercially prepared TLC plates with a flexible backing and a silica-gel coating with a fluorescent

Introduction: This experiment involves an extraction of a natural product using the techniques of steam distillation. The principle component of oil of cloves is an aromatic compound‚ which is identified by thin layer chromatography (TLC). Eugenol is widely used in dentistry‚ due to its analgesic‚ antiseptic balsamic qualities. It is ideal for curative for pulp hyperemia (the soft‚ sensitive substance underneath the enamel and dentine of a tooth) and pulp its. In dentistry eugenol is also used to

To: Wesley Clark From: Lizzie Heath Date: March 4‚ 2013 Subject: Thin-Layer Chromatographic Analysis of Drug Components (Experiment #15) The purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane

of the Experiment: The intention of the experiment is to use solvent extraction methods to separate a mixture containing a carboxylic acid and a neutral compound. Once recovered‚ the solids were purified by recrystallization and examined by thin-layer chromatography‚ and their identities were derived by melting point and infrared (IR) spectroscopy. Extraction is a procedure that selectively dissolves one or more of the mixture compounds into a proper solvent. Extraction refers to the moving
