Zeeman atomic absorption spectrometer RA-915+ for direct determination of mercury in air and complex matrix samples

摘要: Zeeman mercury spectrometer RA-915+ is suitable for the direct determination (without preconcentration step in absorption trap) of concentrations various samples, such as air, water, soil, food, coal, oil and so on with background levels detection limits. The were determined by same using different attachments to convert bound its atomic form. To determine samples complex matrix without pre-treatment (whole blood, hair, crude oil, vegetation, food), a two-chamber pyrolytic atomiser was developed. Its design allows separate processes evaporation dissociation compounds well simplify components gaseous phase real time. Results analyses simple matrices are shown paper.
