The chapter will outline the basic theory, advantages and disadvantages, experimental considerations and set up of various atomic spectroscopy, and electroanalytical quantification methods and their specific application to trace element determination in wines. The reader will gain an introduction to most popular elemental analysis methods used in beverage analysis. Copper, iron, manganese, and zinc will be used as examples of essential trace elements throughout the chapter that at high levels may affect the properties of wine as well as the sensory experience of the consumer. Furthermore, special considerations that should be given to wine as a sample matrix for quantitative analysis of inorganic elements and the use of standard addition methods will be described.

“…The examined species were inorganic mono-and divalent cations [14] and anion [15], which could be found in wine: Li + (500 mg l -1 ), Na + (500 mg l -1 ), NH 4 + (250 mg l -1 ), Mg 2+ (400 mg l -1 ), Ca 2+ (400 mg l -1 ) and SO 3 2-(0.01 mol l -1 ). Ammonia (0.5 mol l -1 ) was also studied because it can be produced during brewing fermentation.…”

“…However, ICP spectroscopy methods are subject to matrix and spectral interferences for lithium analysis [10,20]. Spectral interference are caused by inter-elemental spectra overlapping, especially from sodium and potassium [12,15,21], and other elements or molecules such as calcium, magnesium, chloride, glucose, phosphate and ethanol [15,22,23]. The matrices of various drugs have been found to interfere with lithium analysis as well [10].…”

A sensitive analytical method using mixed mode HPLC separation coupled with charged aerosol detection (CAD) was developed for quantitative analysis of lithium. The method is capable of separating lithium ion from different drug matrices and other ions in a single run thus eliminating the organic matrix and ionic analyte interferences without extensive sample preparation such as derivatization and extraction. The separation space and chromatographic conditions are defined by systematic studies of the retention behaviors of lithium and potential interfering ions and different type of pharmaceutical APIs (active pharmaceutical ingredients) under reversed-phase, HILIC and cation/anion exchange mechanisms. Compared to other current analytical techniques for lithium analysis, the presented method provides a new approach and demonstrates high sensitivity (0.02ng for LOD and 0.08ng for LOQ in both standard and sample solution). The method has been validated for pharmaceutical samples and can be potentially applied to biological, food and environmental samples.
