A GPC Column has crosslinking PS as the stationary phase and THF as the mobile phase, please draw GPC chromatograms of sample mixtures according to the experimental conditions given in the following questions. (5 points) Advices:- refractive index (RI) of PS = 1.0 RI of THF = 0.8 RI of Toluene = 0.9 RI of PMMA = 1.43 a. A PS sample is dissolved in toluene / RI detector b. A mixture of PS (MW = 5,000), PS (MW = 10,000), and PMMA (MW = 80,000, biggest Vh)/THE is used as solvent. / UV detector (Amax = 262 nm, chromopore -C=C- of aromatic ring) (assume: equal concentration of each polymer) c. A mixture of PS (MW = 5,000), PS (MW = 10,000), and PMMA (MW = 80,000, biggest Vh)/THF is used as solvent./ RI detector (assume: equal concentration of each polymer) d. A mixture of PS (MW = 5,000), PS (MW = 10,000), and PS (MW = 20,000) )/THF is used as solvent. / light scattering detector (assume: equal concentration of each polymer) e. A mixture of PS (MW = 50,000) and PMMA (MW = 50,000))/ THE is used as solvent. / Vn of PS is bigger than Vn of PMMA./ viscosity detector (assume: equal concentration of each polymer) A GPC Column has crosslinking PS as the stationary phase and THF as the mobile phase, please draw GPC chromatograms of sample mixtures according to the experimental conditions given in the following questions.
