What device is used for the identification of isotopes of elements having solid-state?
Correct answer: A. Aston spectrometer
- A. Aston spectrometer
- B. Dempster's mass spectrometer
- C. Soddy mass spectrometer
- D. Atomic spectrometer
Explanation
The Aston mass spectrometer was designed to separate and identify isotopes based on their mass-to-charge ratio. It is particularly useful for solid elements that can be vaporized in the instrument. Thus, Aston's spectrometer is the standard device for solid-state isotope identification.

About Analytical Chemistry
Analytical chemistry identifies and measures substances using separation and instrumental methods. Chromatography is studied through stationary and mobile phases, retention and Rf values, while spectroscopy connects absorption of electromagnetic radiation with molecular structure and supports qualitative and quantitative analysis through techniques such as UV-visible and infrared spectroscopy.
