Summary
Frequency-modulated simultaneous Atomic Absorption Spectrometry (FremsAAS) with EDL light sources shows high accuracy and efficiency. This method accurately determined As, Se, and Sb in complex matrices, matching certified values.
Area of Science:
- Analytical Chemistry
- Spectroscopy
Background:
- Atomic Absorption Spectrometry (AAS) is a key analytical technique.
- Enhancing AAS accuracy and efficiency is crucial for trace element analysis.
Purpose of the Study:
- To evaluate the accuracy and efficiency of frequency-modulated simultaneous AAS (FremsAAS) using EDL light sources.
- To establish fundamental calibrations for As, Se, and Sb using FremsAAS.
Main Methods:
- Utilized frequency-modulated simultaneous AAS (FremsAAS) with Electrodeless Discharge Lamps (EDLs).
- Employed graphite furnace and hydride generation with heated quartz tubes for atomization.
- Performed fundamental calibrations for Arsenic (As), Selenium (Se), and Antimony (Sb).
Main Results:
- Characteristic data from FremsAAS were in good agreement with conventional single-channel AAS.
- Accurate determinations of As, Se, and Sb were achieved in complex matrices.
- Results showed complete agreement with certified values in standard reference materials.
Conclusions:
- FremsAAS with EDL light sources is an accurate and efficient method for trace element analysis.
- The established calibration methods are reliable for determining As, Se, and Sb.
- FremsAAS demonstrates suitability for analyzing samples with complex matrices.
