Graphite furnace atomic absorption spectrometry (gfaas) is a method of absorptiometry that proceeds by introducing a tiny quantity—on the order of 10 µl—of a sample into a tubular graphite furnace, atomizing via electrical heating (to 1000–3000°c), and measuring the characteristic optical absorption wavelengths of individual elements.

This book addresses furnace atomic absorption spectroscopy, which has gained worldwide acceptance as an analytical technique. Faas offers 100-1000 times better determination and detection limits than other techniques for a majority of the elements. This technique requires a small sample size, and demands less sample-preparation time than others.
A simultaneous, multielement atomic absorption spectrometer utilizing a graphite furnace atomizer was constructed and evaluated. The optical arrangement employs a concave grating to combine the spectral output from a deuterium lamp and four hollow cathode lamps that are placed on the perimeter of a rowland circle.
