Organogermanium compounds can be mineralized by wet oxidative digestion for 4 h at 70°C, in aqueous potassium persulphate, at pH 12. After dilution to an adequate concentration germanium can be determined by ICP-AES (inductively coupled plasma atomic emission spectrometry)9. 

Prior to analysis, solutions from seven-day T/D tests on cuprous oxide (Cu20) and nickel metal powder (Ni) were passed through a column with iminodiacetate functional groups using an ammonium acetate buffer. The alkali and alkali earth metals are not bound to the column thereby separating the cations associated with the saltwater matrix from the transition metals of interest which are subsequently eluted with nitric acid and analysed by ICP-AES (inductively-coupled plasma-atomic emission spectrometry).

Metals contained in samples are determined by a wide variety of analytical methods. Bulk metals, such as copper in brass or iron in steel, can be analyzed readily by chemical methods such as gravimetry or electrochemistry. However, many metal determinations are for smaller, or trace, quantities. These are determined by various spectroscopic or chromatographic methods, such as atomic absorbance spectrometry using flame (FAAS) or graphite furnace (GFAAS) atomization, atomic emission spectrometry (AES), inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), x-ray fluorescence (XRF), and ion chromatography (IC).

Maintaining the quality of food is a far more complex problem than the quality assurance of non-food products. Analytical methods are an indispensable monitoring tool for controlling levels of substances essential for health and also of toxic substances, including heavy metals. The usual techniques for detecting elements in food are flame atomic absorption spectroscopy (FAAS), graphite furnace atomic absorption spectrometry (GF AAS), hydride generation atomic absorption spectrometry (HG AAS), cold vapour atomic absorption spectrometry (CV AAS), inductively coupled plasma atomic emission spectrometry (ICP AES), inductively coupled plasma mass spectrometry (ICP MS) and neutron activation analysis (NAA). 

About 100 mg of each charcoal sample was wet ashed with nitric and sulphuric acid according to the method described by Bajo et al. and the metal contents of the samples (Na, K, Ca, Mg) were determined with ICP-AES (Inductive Coupled Plasma Atom Emission Spectroscopy, Varian, Model Liberty 110).

Generally the alkali metals (Li, Na, K, Rb, Cs), the alkali earth metals (Mg, Ca, Sr, Ba) and other metals (e.g. Fe, Mn, Si, Al, Cu, Zn, Cr, Co, Ni) are determined in the acid-preserved pore water samples. Analytical details depend on the special conditions provided by the applied analytical instruments ICP-AES (Inductively Coupled Plasma Atomic Emission S.pectrometer), ICP-MS (Inductively Coupled Plasma Mass Spectrometer), or AAS (Atomic Absorption Spectrometer) of the respective laboratory. A discussion of details is not appropriate in this chapter. In most cases dilutions of 1 10 or 1 100 will be measured depending on the salt content in marine environments, so that the required sample amounts are rather low.
