ANALYTICAL SPECTROSCOPY

Atomic-Spectroscopy Theory Atomic-Absorption Spectroscopy Atomic-Emission Spectroscopy

Introduction

Atomic-absorption spectroscopy (AAS) is used to measure the concentration of an element in a sample. There are two main types of instruments: flame AA and graphite-furnace AA. The flame AA provides high precision analyses of aqueous solutions. The graphite-furnace AA provides greater sensitivity and can directly analyze solid samples but it has lower precision than flame AA. In general AA spectrometers can analyze only one or a few elements simultaneously.
