Compare and contrast Column (solid-liquid) chromatography, Paper
Chromatography, and thin layer chromatography in respect to the
size of the sample that can be separated, the ease of use, and the
versatility of the method.
1.How is the retention (capacity) factor manipulated in liquid
chromatography? in gas chromatography?
2. How is the selectivity factor manipulated in liquid
chromatography? in gas chromatography?
3. Briefly describe the general elution problem.
Set up a table and compare and contrast these
4-chromatographic/separation techniques (Gas Chromatography, Liquid
Chromatography, Electrophoresis, Size Exclusion Chromatography).
Make sure to include what characteristic the separation is based
on, the mobile phase, the stationary phases, and an available
detection method for each technique. Thank you!
How do the partition chromatography model and the adsorption
chromatography model differ in their explanations of how
separations occur in column chromatography?
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.

c. The separation of a nonvolatile pollutant found in drinking
water.
d. The...
