    CIVIL ENGINEERING ABSTRACT This report describes a compression test on concrete columns. The main aim of the tests was to illustrate the ultimate strength limit state of reinforced concrete columns in combined bending and compression and to demonstrate the influence of slenderness on the ultimate load capacity. Test methods are described. It was found that the concrete columns exhibited complicated behaviour‚ and had a squash load point of 342.7KN and moment at 0 KN.m‚ a decompression

    Size Exclusion Chromatography Size Exclusion Chromatography (SEC) is the separation technique based on the molecular size of the components. Size exclusion chromatography is a kind of method to separate different size of molecules that put in solution. It was first discovered by two scientists who named Grant Henry Lathe and Colin R Ruthven. Both of them received the John Scott Award for this fabulous invention. There are various applications for Size exclusion chromatography such as biochemical

    Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample

    EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed

    Paper Chromatography Chromatography comes from the Greek word khromatos (color) and graphein (to write); i.e. paper chromatography is literally color writing on paper. This method tests the purity of compounds and identifies substances. This analytical process‚ despite having been replaced by the success of thin layer chromatography‚ still stands as a valuable teaching tool‚ and is nevertheless very common. This method is very useful because not only is it a relatively quick process‚ but also

    Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid
