Rf values for chromatography experiment

These are only approximate measurements, the initial measurements will depend on the screen size of your computer. However, the ratio should give the same answer. We have fairly close agreement with some of the accepted values for this solvent, but a little variation with some others.

Alanine

21/48

0.44

Arginine

13/49

0.27

Aspartic acid

15/48

0.31

Glycine

17/48

0.35

Phenylalanine

0.51

Mixture

17/49

0.35

26/49

0.53

33/49

0.67

This supports the conclusion that the mixture contained glycine, phenylalanine and tyrosine.
