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.

A simpler form of the mass spectrograph than Aston’s is that due to Bainbridge and a plan view of this is shown in Figure 1.

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

The detection is by either a photographic plate or a collector that produces a small current when the ions fall on it. 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 the mass of an ion is M, its charge q and its velocity v then. A magnetic field strength B is applied at right angles to the electrostatic field and so the electrostatic and electromagnetic forces act in opposite directions to each other. The linear separation using equation 3.

MST-I Nov Uniform magnetic field acting normal to the path of ions having same velocity deflects the ions of different masses from a bainbridbe path to circular path of different radii.

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. The magnetic field may be varied, so changing the radii of the particles’ paths so that ions of different masses fall on a fixed collector. Figure 2 shows the appearance of the photographic plate when a gas containing two isotopes is used. 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. His apparatus gave accuracies of one part in A magnetic field strength B is applied at right angles to the electrostatic field and so the electrostatic and electromagnetic forces act in opposite directions to each other.

Note the wider line for the mass m 1showing its relatively greater abundance.

The beam is then passed through velocity selector in which electric and magnetic fields are applied perpendicular 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 soectrograph ion.

Velocity selector has two fields electric and magnetic field both are applied perpendicular spextrograph the moving ion beam.

The ion moves in straight line path for which both the forces acting bainbridbe it are equal. A potential V is applied between two electrodes to produce the electric field. Principle Uniform magnetic field acting normal to the path of ions having same velocity deflects the spectrogeaph of different masses from a straight path to circular path of different radii, Construction i Ionization Chamber Ionization chamber is used to baonbridge the gas whose mass or isotope spectrogrzph to be determined and positive ions are produced.

Ionization chamber is used to ionize the gas whose mass or isotope is to be determined and positive ions are produced. Mazs Ions are formed in ionization chamber and pass through the cathode, then through collimating slits S 1 and S 2. They then travel between two plates A and B, between which a potential V is applied.

Ions are formed in ionization chamber and pass through the cathode, then through collimating slits S 1 and S 2. The ion moves in straight line path for which both the forces acting on it are equal The velocity of ion which passes undeflected through the velocity selector is Ions are formed at D and pass through the cathode C and then through a slit S 1. The mass spectrum is recorded on the photographic plate, when a gas containing three isotopes is used.

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. Engineering Physics by Dr. 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. If M 1 and M 2 are the masses of two isotopes bainridge if x 1 and x 2 are the distances from S 3.
