What are the mechanisms of samples separation work in Thin layer Chromatography? Please shortly answer at your own words. Answer should be to the point (specific 4-5 lines).
4. (14 points) A soil sample (4.00 g) is digested and analyzed for Cd by atomic absorption analysis. The digestion results in 25.0 mL of extract. Because there is concern of matrix effects, standard addition is used. A portion of the extract is analyzed directly by AA and gives an absorbance of 0.211. Another 10.0 mL portion of the extract is spiked with 50.0 ug of Cd (ignore any added volume from Cd spiking) and gives an absorbance of 0.539. a) Calculate the Cd concentration in the (unspiked) extract (in ug/mL). (8 pts) b) Calculate the Cd concentration in the soil in ppm (by mass). (3 pts) c) A Cd standard prepared in dilute nitric acid to a concentration of 1.00 µg/mL is analyzed and gives an absorbance of 0.191. Was the standard addition justified? (3 pts)

hree components in a mixture have varying distribution constants between the mobile phase and the stationary phass One of the components has a very low distribution constant, Would this component likely elute first or last and how would you design an experiment or modify the components of the separation to make it perform in the opposite manner?
cont irmation True or false: The purpose of the internal standard is to make quantitation of the analyte insensitive to injection errors

Researchers used gas chromatography to determine the % v/v methyl salicylate in rubbing alcohol [Van Atta, R. E.; Van Atta, R. L. J. Chem. Educ. 1980, 57, 230-231]. A set of standard additions was prepared by transferring 20.00 mL of rubbing alcohol to separate 25 - mL volumetric flasks and pipeting 0.00 mL, 0.20 mL, and 0.50 mL of methyl salicylate to the flasks. All three flasks were diluted to volume using isopropanol. Analysis of the three samples gave peak heights for methyl salicylate of 57.00 mm, 88.5 mm, and 132.5 mm, respectively. Determine the % v/v methyl salicylate in the rubbing alcohol.
