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

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

About 80 % of the audience appeared to be observing actively. This meeting also had two student representatives. The TLC meeting was conducted to discuss the Student Learning Outcomes (SLO’s) and also to approve some new courses. They talked about the significance of SLOs and their impact on the learning process of the students. They mentioned that‚ the courses are designed

Name: Bill Marano Due Date: 4-1-13 Experiment Title: TLC Analysis of Analgesic Drugs Purpose: The purpose of this experiment is to identify the brand name of an unknown commercial analgesic product by TLC analysis. Unknown #1 solution was run against standard solutions of individual analgesics. The components of the unknown product were identified by comparing characteristic traits‚ such as Rf‚ fluorescence and iodine staining‚ to those exhibited by the standards. The name of the commercial product

The Structure of the Earth and Plate Tectonics Structure of the Earth Mantle • The Earth is made up of 3 main layers: Outer core Inner core – Core – Mantle – Crust Crust The Crust • This is where we live! • The Earth’s crust is made of: Continental Crust Oceanic Crust - thick (10-70km) - buoyant (less dense than oceanic crust) - mostly old - thin (~7 km) - dense (sinks under continental crust) - young How do we know what the Earth is made of? • Geophysical surveys: seismic‚ gravity‚

So let’s see creative strategies of the campaign 1.First of all‚ obviously‚ a creative communication approach was to hijack the common term “T.L.C.”‚ imbuing it with new meaning “tummy loving care.” 2.Secondly‚ they wanted an iconic brand image as a brand for everyone. They choose nation‘s typical ’girl next door’ who might credibly need a little help to keep their tummies on track to convey the message. 3.Except for various common media usages‚ they also creatively designed posters‚ which

Hot Spots During the 1960’s when plate tectonics were coming together‚ it explained the many new things and exposed many other magnificent ideas. This new scientific theory explained a number of mysteries like the movements of continents‚ form of the ocean floor‚ mountain chains‚ volcanoes‚ earthquakes‚ and how ancient life was sorted over time. Determining the behavior of the Earth’s crust‚ from plate tectonics‚ it made it easier for Geologist to focus more on the strange things that happen below

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively
