The analytical advantages of some novel approaches to atomisation using gaseous sample transport and slurry nebulization have been investigated and applied to the determination of trace metals in coal. A cold vapour atomic fluorescence spectroscopic method for the determination of mercury using a gas-sheathed atom cell and front surface illumination was developed. With a manual injection technique the detection limit was 0.01 ng. Replacement with a continuous flow system yielded a more rapid and precise method with a detection limit of C.045 Quantitative recoveries of mercury from a standard coal were obtained through liberation of the analyte using nonoxidative pyrolysis. Continuous hydride generation methods for the determination of arsenic and selenium using atomic absorption and atomic fluorescence spectrometry were developed.
