FAAS stands for which technique?

FAAS stands for which technique?

• A. Flame Atomic Absorption Spectrography
• B. Flame Atomic Absorption Spectrometry
• C. Flame Absorption and Spectrography
• D. Flame Atomic Absorption Spectronomy

Answer: (D)

This tests your ability to recognize how FAAS is expanded as a technique name and what that method entails. FAAS stands for Flame Atomic Absorption Spectrometry. In this method, a dissolved sample is aspirated into a flame to form free atoms of the element of interest. A light source emits radiation at a wavelength specific to that element, and the atoms in the flame absorb part of this light. The amount of light absorbed is proportional to the element’s concentration in the sample, allowing quantification after calibration. The term used for this technique is “spectrometry” (not “spectrography” or the nonstandard “spectronomy”), which is why the correct full name is Flame Atomic Absorption Spectrometry.
