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

Field and laboratory spectrometers usually measure reflectance at many narrow, closely spaced wavelength bands, so that the resulting spectra appear to be continuous curves (Fig. 2).

facultystaff.richmond.eduinvolved in mass spectroscopy. Perhaps the most important use of mass spectrometers in quantitative analysis is as a gas or liquid chromatographic detector. 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.
