Some sources for error are basic human error, like incorrect measurements, and flushing the cartridge at a rate that was too rapid. This experiment could be made better in the future by using a more polar solvent to make sure the separation is the most polar substances first and the least polar substances last.

Any major changes could affect their assessment results. Is Blue 1 Polar? Why is blue the most polar color? What color is the least polar? Why is blue the most polar? Is Red 40 more polar than blue?
How do you know which color is more polar? Is blue dye polar or nonpolar? Is food coloring polar or nonpolar? The contents of the Sep-Pak column stationary phase are very non-polar. Answers and Replies and C-H bonds are considered nonpolar. No hydrocarbon contains a polar structure. Of course, there does exist an EXTREMELY small and probably insignificant difference in the electronegativities of hydrogen and carbon, and thus you have quite the tiny polarity.
What color dye is most polar? The most polar dye is blue No. Is water Polar? A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons. Is NaCl polar? Yes, NaCl is an ionic bond which makes it polar.
A polar molecule consists of atoms having either a positive or negative bond. The difference in electronegativities is what makes a bond polar or nonpolar. How is polarity defined?
