BAINBRIDGE MASS SPECTROGRAPH PDF

Study about Bainbridge Mass Spectrograph, In the Bainbridge mass spectrograph, the positive rays are produced in a specially designed discharge tube ♢. In Bainbridge mass spectrograph, field particles of same velocity are selected by using a velocity selector and then they are subjected to a uniform magnetic field.

The radius of the path in the deflection chamber is directly proportional to the mass of the ion.

Note the wider line for the mass m 1showing its relatively greater abundance. Uniform magnetic field acting normal to the path of ions having same bainbrisge deflects the ions of different masses from a straight path to circular path of different radii. Figure 2 shows the appearance of the photographic plate when a gas containing two isotopes is used.

Ions are formed in ionization chamber and pass through the cathode, then through collimating slits S 1 and S 2. Working Ions are formed in ionization chamber and pass through the cathode, then through collimating slits S 1 and S 2.

A magnetic field strength B is applied at right angles mwss the electrostatic field and so the electrostatic and electromagnetic forces act in opposite directions to each other. A magnetic field strength B spectrogeaph applied at right angles to the electrostatic field and so the electrostatic and electromagnetic forces act in opposite directions to each other.

If the mass of an ion is M, its charge q and its velocity v then or The radius of the path in the deflection chamber is directly proportional to the mass of the ion.

The radius of the path in the deflection chamber is directly proportional to the mass of the ion. Ions are formed at D and pass through the cathode C and then through a slit S 1. Linear separation This method of analysis is very accurate and can detect differences in the masses of two ions as small as one part in 10 9. The detection is done by photographic plate when the ions fall on it.

His apparatus gave accuracies of one part in They then travel dpectrograph two plates A and B, between which a potential V is applied.

MST-I Nov The linear separation using equation 3. Engineering Physics by Dr. This method of analysis is very accurate and can detect differences in the masses of two ions as small as one part in 10 9. This method of analysis is very accurate and can detect differences in the masses of two ions as small as one part in 10 9. A velocity selector was used to produce a monovelocity ion beam and a transverse magnetic field was employed to discriminate between ions of different masses.

If M 1 and M 2 are the masses of two isotopes and if x 1 and x 2 are the distances from S 3. Ionization chamber is used to ionize the gas whose mass or isotope is to be determined and positive ions are produced. The detection is by either a photographic plate or a collector that produces a small current when the ions fall on it.

The ion moves in straight line path for which both the forces acting on it are equal The velocity of mwss which passes undeflected through the velocity selector is If the mass of an ion is M, its charge q and its velocity v then. Velocity selector has two fields electric and magnetic field both are applied perpendicular to the moving ion beam.

Mass spectrometer

The mass spectrum is recorded on the photographic plate, when a gas containing three dpectrograph is used. Amita Maurya, Peoples University, Bhopal.

The beam is then passed through velocity selector in which electric and magnetic fields are applied perpendicular to each other. A potential V is applied between two electrodes to produce the electric field.

Bainbridge Mass Spectrograph – Quantum Study

A simpler form of the mass masw than Aston’s is that due to Bainbridge and a plan view of this is shown in Figure 1. Note the wider line for the mass m 1showing its relatively greater abundance. Bainbridge Mass Spectrograph A velocity selector was used to produce a monovelocity ion beam and a transverse magnetic field was employed to discriminate between ions of different masses.

Mass spectrometer In Aston developed the first really good mass spectrograph, an instrument for measuring the masses of isotopes.
