Column and Thin layer Chromatography of Red Siling Labuyo Marian Angelu Ramos‚ Rose Ann Refuela‚ Leomarie Duanne Sanchez‚ Paula Lynne Santos‚ Geraline Sarmiento‚ Jon Carlo Semana Group number Seven‚ 2E- Pharmacy‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Chromatography is the separation of mixtures into their constituents. It relies on the differential solubilities or absorptivities of the components to be separated with respect to two phases‚ one of which is stationary and the

Chromatography: How can we separate a mixture? Purpose The chromatography lab is to understand how molecules with similar molecular properties can be separated with paper chromatography. These differences will be interpreted to see the distinction of separate chemical substances. Pre Lab Questions 1. Explain capillary action as it pertains to water and paper. Capillary action makes water draw up the paper. As paper absorbs water mixes with the solutions in the paper. 2. What is the

Chromatography – Analyzing Analgesics by TLC and Isolation of β-Carotene by Column Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used

Chromatography (Greek for ‘colour writing’) is used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system‚ thus separating them. Chromatography is necessary in chemical industries‚ as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler forms)

com Liquid Chromatography AP Chemistry Laboratory # 18 Publication No. 10535A Catalog No. AP9093 Introduction In this experiment‚ liquid chromatography is used to separate the substances that are present in grape-flavored Kool-Aid®. First‚ the dyes responsible for the purple color‚ FD&C Blue #1 and Red #40 are separated. Then‚ in a second experiment‚ the other components of Kool-Aid®‚ the flavorings and citric acid‚ are separated as well. Concepts • Resolution • Liquid chromatography • Selectivity

In paper chromatography‚ some compounds in a mixture travel almost as far as the solvent does; some stay much closer to the base line. The distance travelled relative to the solvent is a constant for a particular compound as long as you keep everything else constant. Some compounds may travel farther than others because they may be composed of more components‚ thus traveling farther. For example‚ black is composed of every color of the rainbow‚ while yellow is composed of less colors. As a result

Column Chromatography of Plant Pigments Paul Ibarbia‚ Gene Paolo Jasmin‚ Gianpaolo Jimenez and Lorenzo Labicane* Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column chromatography of plant pigments is the separation of plant pigments extracted from Capsicum frutescens (siling labuyo). No slurry is prepared of the eluent; eluent with the stationary phase is set and then carefully poured into the column. The eluent are the solvents which are responsible for the

Making Candy By. RJ Merna In the Article “The Sweet Science Of Candy Making” by Tom Husband‚ the article explains how different types of candy are made‚ such as chewy (fudge)‚ gritty (cotton candy)‚ or hard (glass candy). You can make fudge by continuously stirring the sugar syrup after a period of cooling‚ so when the sugar crystals form‚ they stay very small and do not grow that to be big. You can make cotton candy or glass by cooling the syrup quickly to keep the crystals from forming. The
