Conclusions

1. A method for the quantitative evaluation of thin-layer chromatograms of dansylglycine by photographing them and microphotometering the negative obtained has been proposed.

2. The method is applicable to amounts of 1·10−10–1·10−9 mole of dansylglycine per spot with an accuracy of ±3%.

3. It is proposed to obtain dansyl amino acids by using dioxane as solvent, which completely prevents the parasitic formation of dansylamide.
