This article focuses on biological sample preparation methods which are unique to each of the commonly used instrumental techniques used in trace element analysis. The biological samples covered are mainly of human and animal origin. The preparation methods considered span the entire gamut and include direct solid or liquid sample introduction involving dilution or matrix modification; dry ashing; wet oxidation including microwave digestion and high‐pressure ashing; deproteinization; and tissue solubilization. The instrumental techniques covered are flame atomic absorption spectrometry (FAAS), graphite furnace atomic absorption spectrometry (GFAAS), inductively coupled plasma atomic emission spectrometry (ICPAES), inductively coupled plasma mass spectrometry (ICPMS), X‐ray fluorescence (XRF) spectrometry, neutron activation analysis (NAA) and anodic stripping voltammetry (ASV). The choice of a given sample preparation method would be governed in general by the type of biological matrix, sample size and the type of instrumental technique used. The advantages and disadvantages of the various sample preparation methods have been emphasized for each of the instrumental techniques. Also, an attempt has been made to point out the optimum sample preparation method(s) suitable for the particular biological matrix and instrumental technique.

Sampling, storing, sample pretreatment, and experimental conditions for selenium (Se) determination in human serum, plasma, and whole blood by X-ray emission spectrometric (XRS) methods are described. Concentration levels in these biological fluids, found by this technique, are discussed and compared to values found by other techniques for the same healthy population group in the same area. XRS analysis of blood from patients with various pathological conditions is reviewed, with special attention to the relation of Se with the concentration level of other essential or nonessential trace elements.
