Summary
Inaccurate values are often obtained in the determination of molybdenum and tungsten in difficult complex matrices — ores, processing and metallurgical products. The main reason for this effect is due to spectral interferences. Background equivalent concentrations caused by changes of background nearby the measured spectral line are calculated for the established interferent matrix elements. It is possible with the applied sample treatment to perform successful analyses of samples with very variable matrix composition.
