Voltammetry of the eight amino acids added to the flame plasma. Showing the colour coded chemical structures a and the corresponding voltammograms b in a flame containing glycine, alanine, serine, leucine, isoleucine, phenylalanine, tyrosine, introduced into the flame by atomised aqueous solutions of 5 mM, except for tyrosine which was 1 mM
