As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase

Introduction Paper chromatography is a method using a chromatography paper to identify the many mixtures of one simple color. The word chromatography comes from the Greek words‚ "chroma‚" meaning color‚ and "grafein‚" meaning to write. The process of this experiment is to place a colored dot‚ such as marker ink‚ onto the chromatography paper‚ one centimeter away from the triangular tip. Next dip your chromatography paper into the solvent‚ not allowing it to touch the colored dot. Let it sit for

Paper chromatography Presented by – Miss. Shruti Vilas Kharat. SYBSc / FS13164 History- Paper Chromatography (PC) was first introduced by German scientist Christian Friedrich Schonbein (1865). PC is considered to be the simplest and most widely used of the chromatographic techniques because of its applicability to isolation‚ identification and quantitative determination of organic and inorganic compounds. Definition- Paper chromatography is an analytical method technique for separating and

Separation and Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this

Chemistry 100 Experiment #2: Chromatography of Food Dyes Name: Cassandra DeVaux Date: April 17‚ 2014 Purpose: To learn how mixtures of compounds can be separated and what food dyes are found in certain foods Introduction: In this exercise we will separate food dyes from a variety of sources. We will first gather data on known dyes where we know how many substances make up the dye. Then we will collect data on some samples where we do not know the make-up. We will compare our

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

When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color
