STPF determination of trace metals in fly ash samples

Summary Some examples are reported of practical applications of the Stabilized Temperature Platform Furnace (STPF) procedure and Zeeman background correction in the determination of trace elements in environmental matrices. Selection of optimal working conditions (wavelength, modifier type, sample volume, thermal program, etc.) is often important in reducing the aspecific absorption to values which can be easily corrected by current systems. Use of the Pd/Mg(NO3)2 matrix modifier along with the Zeeman correction system allows several elements (As, Cd, Sb, Se, Tl, etc.) to be determined in various environmental matrices by direct calibration with aqueous solutions of the analyte.
