High-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS) was used to develop an analytical method for chromium determination in pharmaceutical drugs through direct analysis of solid samples. The limit of detection and quantification were, respectively, 2.9μgkg−1 and 9.7μgkg−1 and the characteristic mass was 2.0pg. Eighteen pharmaceutical drugs and three excipients...
A method has been developed for the determination of lead in biomass, bio-oil, pyrolysis aqueous phase, and biomass ashes by high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS) and direct solid or liquid sample analysis. All measurements were performed without chemical modifier and calibration could be carried out using aqueous standard solutions. A pyrolysis...
