שאלה | Three different methods are used to determine molecular weight distribution by separating the different molecular weight fractions. These methods are Fractional solution (FS), fractional precipitation (FP) and gel permeation chromatography (GPC): Which of the following statements on the sequence in which the different molecular weights are separat d by each method is true? (Choose from the following four possibilities)

(Choose from the following four possibilities)

		The low molecular weight fra tion is first separated in each of the method (FS, FP and GPC)
		The low molecular weight fraction is removed first in GPC, FP but not in FS.
		The low molecular weight fraction is removed first in FS but not in GPC, FP.
		The low molecular weight fraction is removed first in FP but not in GPC or FS.
