WebFeb 14, 2024 · The angular dispersion of a monochromator is defined as the change in the angle of reflection (see the angle r in Figure 7.3.7) for a change in wavelength, or dr / dλ. Taking the derivative of Equation 7.3.5 for a fixed angle of incidence (see the angle i in Figure 7.3.7) gives the angular dispersion as. dr dλ = n dcosr. dyom ix englishWebFunction: Ultrafast separations and excellent resolution on columns with small particles.
