Voltammetry and in situ MS in flame plasma containing simple organic compounds. a Voltammograms of flame containing of methanoic acid, ethanoic acid and alanine, methanol, ethanol and serine, methylamine and glycine, phenol, tyrosine and phenylalanine, introduced into the flame by atomised aqueous solutions of 5 mM, except for tyrosine which was 1 mM. b The mass spectra of the flame containing methanoic acid, ethanoic acid, methanol and ethanol, all corrected for the background flame containing deionised water. Coloured arrows indicate masses of interest
