Dr.Tawfeq al.Qaimare Rifqa Shawer Lab report 5 21-3-2013 Adsorption Chromatography Introduction: The technique of adsorption chromatography may be illustrated by a description of how two dyes are separated when a solution of the dyes is passed through a column of powdered silica contained in a vertical glass tube‚ it’s a method used to separate solids or liquids. At the first the two dyes are adsorbed at the top of the column‚ giving this region a nearly dark blue color. However‚ when

scene report Introduction A suspected white powder was seized from the crime scene and sent to the laboratory for analysis. Presumptive test was firstly used in order to find out if it was a positive drug‚ in order to follow a further analysis. Gas Chromatogram (GC) and mass spectrum was used for further analysis‚ in order to find out what exactly was this drug‚ and find its mixtures and compounds. Results From the chromatogram/spectrum peak report it is shown that there are two retention times

In conclusion‚ the original sample was used to collect different amounts of fraction. The original sample was Spirulina‚ which was spun down in a centrifuge before using. This process helps to separate the proteins from the tissues. Table 1 shows the amount of fraction collected from each sample. Based off the collected fractions‚ there is a larger quantity of yellow fraction present than the blue fraction. The yellow fraction remained in the filter for a longer period of time than the blue fraction

Title of experiment 3: Gel Filtration Chromatography of LDH INTRODUCTION Gel filtration chromatography is a type of column chromatography in which separated protein‚ peptides and amino acids on their molecular size. The stationary phase consists of beads containing pores. The mobile phase is the solvent that is found both around the beads and in the pores of the stationary phase matrix. As the sample is passes through the column‚ the molecule that are larger than the pores will not retarded by

------------------------------------------------- Abstract In the last few decades‚ membrane technology has been a great attention for gas separation technology especially for natural gas sweetening. The intrinsic character of membranes makes them fit for process escalation‚ and this versatility could be the significant factor to induce membrane technology in most gas separation areas. Membranes were synthesized with various materials which depended on the applications. The fabrication of polymeric
