Standard and sample manipulation for calibration in flame atomic absorption spectrometry
thesis
posted on 2018-05-23, 16:02 authored by Stephen R. BysouthThis thesis describes a study of existing calibration
methods and a comparison of them, with novel calibration
and sample pre-treatment methods for flame atomic
absorption spectrometry (FAAS) developed by the author.
A comparison of commercially available curve fitting
algorithms was carried out to show how concentration
errors arise and vary, due to the use of different
empirical models for the calibration curve.
Novel online dilution manifolds were designed. Using
flow injection and continuous flow techniques, different
calibration procedures were developed to allow null
methods of calibration to be used and to extend the
calibration range.
Methods of sample pre-treatment were developed,
including online dissolution and species separation, using
flow injection analysis techniques.
Members of the atomic spectroscopy group of the Royal
Society of Chemistry were surveyed to discover calibration
practices used in commercial laboratories. Respondents
were asked questions on sample type, treatment and
presentation, and data reduction for calibration.
During the research, several papers were published
and lectures given on the topics described.
