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. If M 1 and M 2 are the masses of two isotopes and if x 1 and x 2 are the distances from Bbainbridge 3.

The beam is then passed bzinbridge velocity selector in which electric and magnetic fields are applied perpendicular to each other. A magnetic field strength B is applied at right angles to the electrostatic field and so the baijbridge and electromagnetic forces act in opposite directions to each other.

Ionization chamber is used to ionize the gas whose mass or isotope is to be determined and positive ions are produced. Uniform magnetic field acting normal to the path of ions having same velocity deflects the ions of different masses from a straight path to circular path of different radii.

Principle Uniform magnetic field acting normal to the path of ions having same velocity deflects the ions of different masses from a straight path to circular path of different radii, Construction i Ionization Chamber Zpectrograph chamber is used to ionize the gas whose mass or isotope is to be determined and positive ions are produced.

The mass spectrum is recorded on the photographic plate, when a gas containing three isotopes is used.

The magnetic field may be varied, so changing the radii of the particles’ paths so that ions masa different masses fall on a fixed collector. 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.

MST-I Nov Mass spectrometer In Aston developed the first really good mass spectrograph, an instrument for measuring the masses of isotopes. 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. 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 ion moves in straight line path for which both the forces acting on it are equal.

The detection is done by photographic plate when the ions fall on it. The detection is by either a photographic plate or a collector that produces a small current when the ions fall on it. Ions are formed at D and pass through the cathode C and then through a slit S 1. Note the wider line for the mass m 1showing its relatively greater abundance. His apparatus gave accuracies of one part in Note the wider line for the mass m 1showing its relatively greater abundance.

Figure 2 shows the appearance of the photographic plate when a gas containing two isotopes is used. 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. 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.

Ions are formed in ionization chamber and bwinbridge through the cathode, then through collimating slits S 1 and S spectrogrwph. The radius of the path in the deflection chamber is directly proportional to the mass of the ion.

The linear separation using equation 3. If the mass of an ion is M, its charge q and its velocity v then. The radius of the path in the deflection chamber is directly proportional to the mass of the ion. Working Ions are formed in ionization chamber and pass through the cathode, then through collimating slits S 1 and S 2.

Mass spectrometer

Velocity selector has two fields electric and magnetic field both are applied perpendicular to the moving ion beam. 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. The ion moves in straight line path for which vainbridge the forces acting on it are equal The velocity of ion which passes undeflected through the velocity selector is A potential V is applied between soectrograph electrodes to produce the electric field.

They then travel between two plates A and B, between which a potential V is applied. A velocity selector spectrkgraph used to produce a monovelocity ion beam and a transverse magnetic field was employed to discriminate between ions of different masses. Engineering Physics by Dr.
