Homework Help: Methods for Quantitating Impurity

  1. Apr 1, 2012 #1
    1. The problem statement, all variables and given/known data
    Which of the following allows you to quantitatively determine the composition of a crude product after synthesis? Explain.
    a. NMR
    b. melting point
    c. TLC

    2. Relevant equations

    3. The attempt at a solution
    I know that TLC is used for determining whether an impurity is present or not, so I don't think it can determine how much of an impurity there is. I'm not sure about NMR and melting point though. Please help?

    What quantitative methods do you know? How do they work?

    What is the integration curve in NMR?
