Problem 3. Choose Proper Technique(s) 120 points] Indicate ALL technique(s) from the given list that can be used to solve the following problems. Then, indicate the technique that will give the best result. Explain all of your answer in details. You can also give an answer that none of the available instrument can do the job. Available instruments - X-ray diffraction (XRD) - Low Energy Electron Diffraction (LEED) X-ray photoelectron spectroscopy (XPS) - Ion Scattering Spectroscopy (ISS) - Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) - Flame Atomic Absorption Spectroscopy (AAS) UV/Visible Spectroscopy (UV/Vis) - Fourier Transform Infrared Spectroscopy (FTIR) - Raman Spectroscopy (Raman) a.) [4 points] Which technique(s) can identify the presence of hydrogen atoms in a solid sample? b.) [4 points] To measure salt content in potato chips. c.) [4 points] To verify whether two types of polymer that are blended together form cross- linking or not.
