Hypothesis
The integration of a graphite furnace atomic absorption spectrometer with high pressure liquid chromatography can improve the identification of trace element compounds.
Conclusion
The developed HPLC-GFAAS system can effectively analyze mixtures of arsenic compounds with a sampling rate of one aliquot every 50 seconds.
Supporting Evidence
- The system can analyze an aliquot every 50 seconds.
- Results are printed in tabular form providing retention times and signal intensities.
- Mixtures of arsenic compounds were successfully separated.
Takeaway
This study created a new system that helps scientists find tiny amounts of certain elements in complex mixtures quickly and easily.
Methodology
A computerized interface was constructed to connect a Waters HPLC with an Instrument Laboratory Model IL-555/51 GFAAS, allowing for automated analysis of samples.
