COURSE DESCRIPTION: This course gives an account of  main analytical methods currently employed for determining chemical elements (metals and most of the non-metals) at the trace level.
Such methods are of a particular relevance in various scientific and technological fields, such as:

• Environment monitoring and protection
• Material Science and Metallurgy
• Medicine and Toxicology
• Forensic Science
• Art Conservation

Hot topic:  The Continuum Source Atomic Absorption Spectrometer. A standard atomic absorption spectrometer needs a specific light source for each chemical element. Light emitted by the source has a line spectrum. This makes impractical the simultaneous determination of more elements, but allows using simple and cheap monochromators. The newly developed Continuum Source Atomic Absorption Spectrometer is fitted with a single source which emits white light (i.e. light with a continuum spectrum). The specific radiation is selected by a high resolution monochromator. Fast sequential multi-element analysis and improved simultaneous background correction are the main advantages of this method.
