Gel permeantion chromatography can be used to separate which of the following:
(1) Lanthanides
(2) Alkaline earths
(3) Fatty acids
(4) Low molecular weight peptides
The correct answer is
(a)A and B
(b)B and C
(c)C and D
(d)A and D
Answer
Answer (as printed): C
Explanation
Gel permeation chromatography is a size exclusion chromatography, that separates analytes on the basis of size. So, the size difference in fatty acids and low molecular weight peptides is greater so they can be separated by using gel permeation chromatography.
