ICP-AES stands for which analytical technique?

• A. Inductively Coupled Plasma Atomic Emission Spectrometry
• B. Ion Chromatography Atomic Emission Spectrometry
• C. Inductively Coupled Plasma Atomic Emission Spectroscopy
• D. Infrared Coupled Plasma Ambient Emission Spectrometry

Answer: (A)

The technique relies on emitting light to identify and quantify elements. In ICP-AES, a sample is introduced into a high-temperature argon plasma that excites the atoms present. Those excited atoms emit light at wavelengths unique to each element, and measuring the intensity of that emitted light gives you the element’s concentration. The phrase Inductively Coupled Plasma identifies the hot plasma source created by inductive RF energy, while Atomic Emission Spectrometry tells you that the detection method is based on the light emitted by atoms after excitation. This combination is why this naming is the correct one for ICP-AES. The other options mix in a separation technique (ion chromatography) or use a nonstandard or broader naming (spectroscopy vs emission spectrometry), which don’t match how the method is defined.
