“…Older photometric methods are described in the literature (e.g., Burger 1973). For a comparative study of the most commonly employed methods in the analysis of biological materials, see Miller-Ihli and Wolf (1986) and Angerer and Schaller (1985). Analytical methods for Co and Ni were comprehensively reviewed by Stoeppler and Ostapczuk (1992).…”

“…Resonance lines for the elements Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Se, Sn, V and Zn could thus be recorded simultaneously, and the calculated absorbances were all shot noise limited. Similar systems were used by several groups for many fundamental [71][72][73][74][75][76][77][78][79][80][81][82][83][84] as well as applied [85][86][87][88][89][90][91][92][93][94][95] studies, and are also described in a number of overview papers [96][97][98][99][100]. In a detailed analysis [97], O'Haver and Messman stated that the undoubted advantages, in particular flexibility and excellent background correction, were unfortunately counterbalanced by the disadvantage that for elements with resonance lines at wavelengths shorter than 250 nm LODs were significantly poorer with CS AAS than with LS AAS.…”

Since food is the primary source of essential elements for humans, the accurate and precise analysis of food materials is critical. The methods best suited to meet this task are atomic spectroscopic methods such as atomic absorption, atomic emission, and elemental mass spectrometry (MS). Methods commonly used in the generation of food composition data include flame atomic absorption spectrometry (FAAS), graphite furnace atomic absorption spectrometry (GFAAS), inductively coupled plasma atomic emission spectrometry (ICP/AES), and more recently, inductively coupled plasma mass spectrometry (ICP/MS). FAAS and ICP/AES offer similar detection limits (DLs) (ng mL −1 levels), whereas, GFAAS and ICP/MS can provide sub‐ng mL −1 detection capability. The choice of a method often depends on detection capability, but ease of use, speed of analysis, and cost must be considered. ICP/AES and ICP/MS offer the advantage of providing simultaneous multielement measurements, making them well suited for the analysis of large numbers of elements in food samples. If one or a few elements are to be determined, less expensive atomic absorption spectrometry (AAS) methods might be more suitable. The most critical stage in the development of analytical methods is sample preparation. Samples can be prepared using numerous procedures, but the most useful for a wide range of analytes and sample matrices are based on dry ashing or wet ashing of the sample. In addition to total element determinations, speciation measurements are important to determine the exact form of the element that is present in the sample. Since the bioavailability of an element is dependent on its chemical form (speciation), the development of reliable methods for identification and quantification of trace element species is critical. The coupling of chromatographic separation and atomic spectroscopic detection has proven useful for elemental speciation measurements.
