Which of the following is a nondestructive technique for identifying and quantifying trace elements in a test sample?

Question

Quizplus · Accepted Answer

Neutron activation analysis is a nondestructive technique that exposes a sample to neutron radiation, which causes the elements in the sample to emit characteristic gamma rays. These gamma rays can be detected and used to identify and quantify the trace elements in the sample without destroying it. The other techniques listed involve some form of destruction or alteration of the sample, such as burning it (pyrolysis), exposing it to high heat (carbon arc emission spectrometry), or breaking it down into individual particles (microscopic examination). ICP emission spectrometry is also a form of atomic spectroscopy that involves the destruction of the sample.
