1. Sketch diagrams of a gas chromatograph and a high performance liquid chromatograph. Label all the parts and describe their use in one sentence each. Why is HPLC so important to modern industrial chemistry?

Solutions

Expert Solution

HPLC using liquid as mobile phase, can analyze compounds which can be dissolved in liquid. Volatility is not that important here. Immediately, we see HPLC can be used on much more analytes than GC, because there are a lot of non-volatile compounds can be dissolved in water, methanol, acetonitrile, acetone, or hexane, etc. Therefore, currently, HPLC is used more often than GC.

1. In this experiment we injected the sample to be analyzed by Gas Chromatograph equipped with an FID (Flame Ionization Detector). The detector ionizes the sample as it reaches it, and the peak is proportional to the number of ions with a live flame. Explain in detail, why we need to run a standard when the GC is equipped with an FID detector to identify the component in a sample?

Sketch and label the following thermodynamic processes on enthalpy-temperature or internal energy-temperature diagrams (as appropriate). Use a separate diagram for each case. Clearly label reactant and product conditions on each diagram as well as the direction of the process path. For each process, specify (a) what initial conditions/inputs must be provided, (b) what resulting reaction quantity of interest can be calculated, (c) what thermodynamic constraints/assumptions apply, and (d) why you chose each diagram as well as why you drew each...

Draw free body diagrams for the motorcycle rider for each of the following situations. Label all your force vectors clearly, and draw them in a self-consistent manner – that is, forces that cancel (sum to zero) should be drawn so that they cancel on your diagram. In all diagrams, assume the motion is towards the right. A motorcycle rider falls off her Harley while attempting to pop a wheelie. The motorcycle rider skids along the surface of a horizontal road,...
