Beam Chopping corrects for flame emission but not for scattering. Can distinguish the signal of the flame from the atomic line at the same wavelength. The higher the absorbance the higher the transmittance. Intro to IR Near IR- (0.78 to 2.8 micrometers) Mid IR- (2.5- 50 micrometers) Far IR- (50-1000 micrometers) Most common region used is Mid IR btwn 2.5- 15 micrometers Mid IR: based on diffracting gratings but now current instrumentation are of Fourier transform type Far-IR: useful
