HPLC–CLND for the Analysis of Underivatized Amino Acids

The use of ozone-induced chemiluminescence detection in chromatography has been reviewed recently (21–24). Briefly, HPLC column effluent is nebulized with oxygen and argon or helium and introduced into a pyrolysis tube heated to 1050 °C. In an oxygen-rich environment the mobile phase and the solutes are oxidized into oxides (water, carbon dioxide and other oxides). All the nitrogen …
