Techniques {nephelometry} can measure light scattered at right angles to light path. At dilute concentrations, absorbance is directly proportional to scattering coefficient, path length, and concentration, as in Beer's law. Particle sizes, particle shapes, solution pH, temperature, and mixing can change scattering. Scattering is more if wavelength is less, so UV light causes more scattering. Nephelometry is 10 times more sensitive than turbidimetry.
