Question

State which separation technique (Gas Chromatography, Liquid Chromatography, Electrophoresis, Size Exclusion Chromatography) would be the best choice for each of the cases below and explain WHY? thank you!
a. Separation of volatile components found in a perfume and that result in its characteristic fragrance.
b. The determination of the molecular weight of a polymer that was synthesized by a   friend in a polymer synthesis lab. Fall 2017
c. The separation of a nonvolatile pollutant found in drinking water.
d. The separation of two similarly sized amino acids.
e. The separation of Albumin and Gamma-Globulin.
f. The separation of a mixture of elicit drugs.

Answer 1

a. Separation of volatile components found in a perfume and that result in its characteristic fragrance : GC-MS is preferble seperation technic because samples are allowed into the GC in vapor state.

b. The determination of the molecular weight of a polymer that was synthesized by a friend in a polymer synthesis lab. Fall 2017: Size Exclusion Chromatography is preferable because polymers are highly molecular weight.

c. The separation of a nonvolatile pollutant found in drinking water:  Liquid Chromatography is preferable because of analyts distibusion

d. The separation of two similarly sized amino acids: Electrophoresis is preferable because of migtration velocities of amino acids.

e. The separation of Albumin and Gamma-Globulin Size Exclusion Chromatography is preferable because Globulin is protein, which is highly molecular weight.

f. The separation of a mixture of elicit drugs :Liquid Chromatography
