Concept explainers
To calculate:The radius of curvature must a spectrometer have.
Given information:
From a mass spectrometer, it is difficult to separate molecules with nearly equal mass such as CO(28.0106u) and N2(28.0134u). These two molecules are to be separated on the film by 0.50mm.
Formula used:
Calculation:
The particle in mass spectrometer follow semicircular path.
From
Here
Now,
The distance between the point of entering to the point of striking the film is 2r
The two molecules are separated on the film by 0.50 mm. Difference in radii of two molecules is0.25mm
