What does GFAA stand for?

In atomic absorption spectroscopy, the name tells you how the sample is prepared and how the measurement is made. GFAA specifically uses a graphite furnace to atomize the sample, and it measures absorption of light by atoms at characteristic wavelengths. So the full, conventional name is Graphite Furnace Atomic Absorption Spectrometry. That’s why the option that includes Graphite Furnace Atomic Absorption and notes spectrometry is the correct one. The other choices mix up the method (emission vs absorption), the flame versus graphite furnace atomization, or point to a different technique altogether (like ICP-OES).
