Construction of flame spectrometers Most parts of flame spectroneters are very similar or the same, thus the commercial flame atomic absorption spectrometers can be used as flame emission spectrometers as well (Fig 1). In case of FES the examinated particles (excited atoms) are produced by the flame itself. For

A more recent innovation is the use of an inductively coupled plasma (ICP) as an ion source for a mass spectrometer; this combination (ICP-MS) is a powerful tool for elemental analysis.
