Chromatography usually involves two different phases. What names are given to these two phases?
Why are chromatograms spotted with amino acid solutions often sprayed with ninhydrin after the chromatography is complete?
A chromatography experiment was performed on five different solutions of amino acids (A–E). A contained cysteine, B contained glycine, C contained alanine, D contained valine, and E contained an unknown mixture of amino acids. By inspecting the chromatogram shown, which of the amino acids are present in solution E?
