A supersonic jet fluorimeter with a spectrometric multichannel analyzer allows repetitive measurements of a fluorescence spectrum for gas chromatograph effluents. A three-dimensional chromatogram is measured for a sample containing chloroanthracene derivatives by adjusting the excitation wavelength to that of a pure electronic transition for a specified molecule. By using this method, the sample molecule can readily be identified from wellresolved spectral features in the fluorescence spectrum.
