1. In this experiment we injected the sample to be analyzed byGas Chromatograph equipped with an FID (Flame Ionization Detector).The detector ionizes the sample as it reaches it, and the peak isproportional to the number of ions with a live flame. Explain indetail, why we need to run a standard when the GC is equipped withan FID detector to identify the component in a sample?
2. Gas Chromatography is another chromatography method you arelearning about this semester. Construct a table comparing andcontrasting the two other chromatography methods (TLC and LC).Point out to differences and similarities between each method andthe GC method. Give at least 4 criteria of comparison.
3. During last week’s lab of distillation, many of you haddifficulties getting the fractional distillation column to workproperly. Specifically, the liquid started condensing at the top ofthe fractional column and the vapor did not distill over. The labinstructor suggested that changing the bead size (which was in thecolumn) to a larger size might improve the outcome of theexperiment. Is this suggestion valid? Would it help the process oris this suggestion wrong? Explain your answer.
