Question

Describe with theory of Aston's mass-spectrograph.​

Answer 1

Answer:

Passing the beam between the poles of a large magnet then deflected the ions' paths according to their mass; by tuning the electric field, ions of different mass could be brought to focus on a photographic plate. Because the device was set up like Gustav Kirchhoff's spectroscope, Aston named it a mass spectrograph.

mass spectrometers and mass spectrographs, and they operate on the principle that moving ions may be deflected by electric and magnetic fields. The two instruments differ only in the way in which the sorted charged particles are detected.

Answer 2

Theory of Aston's mass-spectrograph:

• Aston's mass-spectrograph is a device to separate electrically charged particles of different masses and accurately measure the mass of these electrically charged particles. This instrument has been widely used in the medical field.
• It is also used in nuclear physics, geology, chemistry. This instrument was discovered by Dr. Francis William Aston. He won Noble prize in chemistry in the year 1922 for discovering mass spectrometer. He passed away in the year 1945.
