- In a sample consisting of lysine, leucine, and glutamic acid, which will be eluted last from an anion exhange resin at pH7?estimate the composition of these initial samples of distillate using figure 1. Based on the results what conclusion can you draw regarding the relative efficiencies of the two separations?what is the difference between liquid phase extraction and solid phase extraction?
- Give the advantages and disadvantages of sequential injection analyzers compared to traditional flow Injection analyzers.Determine the order of inhibition time of hexane, hexanol and benzene compounds in the reverse phase liquid chromatography column.Of Aspirin, ethanol, acetaminophen, ethyl acetate, hexane, and water which could go undetected during HPLC analysis, but could result in a lower than expected melting point, why are they not detected by HPLC analysis?
- Calculate the amount of phycocyanin in Sample 1 in mg where A620 = 0.193 and A650 = 0.095, taking into account the dilution factor of 100 ul, and the total volume of extract 45ml. Note your answer to 2 decimal places.Summarize the Experimental Procedures(Part A, B, C IN YOUR OWN WORDS AND IN BULLET POINTS: Experimental Procedure for Part B: Place each compound in the first column in a well of aspot plate. If a compound is a solid and not a liquid, add a small amount of water to it and stir.For all solutions, use 0.1 M provided in lab. Use a conductivity device to determine if thesubstance is conducting or not. Record the relative brightness of the light or absence of light. A bright light only indicates more ions are in solution compared to a dim light, not whether it is a strong or weak electrolyte. The concentration of ions must be known to make a more definitive conclusion. The absence of a light indicates that ions are not present. Only the ends of the two copper probes of the device should be in the solution. On the back of theconductivity device is a guide for you to use. Experimental Procedure for Part C: Add approximately 2-3 drops of each pair of reactants in the first column to a test…At the completion of the experiment, a student measures the solvent front to be 55 mm from the baseline. If a component in the sample being analyzed generates a spot whose diameter spans from 34 to 36 mm from the baseline, calculate the Rf value for that component.
