- PAPER CROMATOGRAPHY • Define chromatography • Demonstrate an understanding of the process of chromatography • Describe the steps involved in a chromatography investigation Explanation Coloured inks are often made up of several different inks. Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup . Water • Scissors III. Health and safety • Make sure that you thoroughly clean any equipment after the experiment before using for food IV. Procedure Method 1 1. Take a sheet of kitchen roll and draw a simple picture with a non-washable felt tip pen. 2. Place the sheet over an empty bowl. This is to keep the paper from getting too wet. 3. Carefully add a few drops of water…Explain the following Chromatography (for drug analysis) Thin-layer chromatography (TLC) Gas chromatography (GC) Liquid chromatography (LC) (i.e, high performance liquid chromatography or HPLC)Chemistry Briefly describe the differences between the scanning and SIM approaches with reference to your data. Discuss how and why your scanning (TIC) and SIM (mass chromatograms look different. Pay particular attention to selectivity of compounds detected and signal-to-noise. What are some advantages of SIM? What are some disadvantages?
- Which one is the most common method used for the purification of liquid mixtures? Filtration Chromatography Evaporation DistillationWhat is paper chromatography please include the importance of using itIn normal-phase HPLC chromatography, the stationary phase is polar and the mobile phase is nonpolar. In the reversed phase we have just the opposite; the stationary phase is nonpolar and the mobile phase is polar. Describe molecules in which move faster or slower in each case.
- Describe what is chromatography?How else can chromatography be used? None of these answers are correct. To wash (or remove) unwanted solvents from a mixture. To identify or exclude components in a mixture. To generate IUPAC names for hydrocarbons.Describe chromatography analysis, the two essential phases used in paper chromatography and provide an example.
