Analytical consideration and methodologies for elemental determinations in biological samples
1991
Akey, D.H. | Burns, D.W.
Available analytic methods for elemental determinations of biological samples are reviewed and discussed. Preparation of samples (including wet digestions and dry ashing techniques), analytical standards, and analytical blanks are considered. Current practices of elemental marking techniques and of the use of inherent elemental composition as a marker in itself are presented. Specifically, atomic absorption spectroscopy, inductively-coupled plasma atomic emission, X-ray fluorescent spectroscopy, neutron-activation analysis, laser-enhanced flame ionization, and mass spectrometry are considered in respect to elemental analysis of plant and arthropod samples. Emphasis is placed on atomic absorption and prerequisite sample preparation because of the practicality of the technique and its present widespread use.
