Bragg's Law
From Bragg’s Law two important postulates can be asserted:
- A given energy photons are reflected only at certain angle that depends only on the properties of the scattering material.
- A scattering reflector set on a particular angle will reflect only certain photons out of a polychromatic beam. Those, the energy of which fulfills the Bragg’ Law.
It is worth mentioning that the use of a monochromator does not necessarily imply better detection limits. This is particularly true for the low energy zone of the analytical lines.
