Water uptake affects light scattering by particles due to changing the particle size and the index of refraction. This has been discussed in detail in Chapter 9.B.4 and the reader is referred to that section for more... 

The full extinction Cext will be observed only if the detector subtends a sufficiently small solid angle. As the detector is moved closer to the particle, however, the observed extinction will decrease. We shall see when we consider specific examples that light scattered by particles much larger than the wavelength of the incident light tends to be concentrated around the forward direction. Therefore, the larger the particle, the more difficult it is to exclude scattered light from the detector.

Here fj(k) is the field amplitude of the light scattered by particle j with its center of mass at the position ry, Nis the number of particles in the scattering volume, K = K/ — K is the transferred momentum, and k = K. For elastic scattering K, = K/ = 2tuis/2q, where is the incident light wavelength in vacuum. Thus,...

Light-scattering techniques (Figure 39) are primarily used to investigate aerosols and air pollutants. They analyze the light scattered by particles if they... 

The moment is proportional to the total light scattering by particles when they are much smaller than the wavelength of the incident light. The scattering efficiency of a. small single spherical partide —that is, the fraction of the light incident on the particle that... 

The intensity of light scattered by particle that is a Rayleigh scatterer is thus proportional to the square of particle volume and inversely proportional to the fourth power of wavelength of an incident beam, i.e. 

Yamazaki et al. (1992) calibrated his probe (Figure 4-12) and in a liquid-solid stirred mixer. Figure 4-13 gives the calibration curves for different particles. It shows that particles of different sizes and materials have different sensitivities and linear regions. Saturation may occur because of light scattering by particles of different surfaces and concentrations.

A colloidal sol is a suspension of very small solid particles in a continuous liquid medium. Colloidal sols are quite stable and show the Tyndall effect (light scattering by particles in a colloid). They can be quite stable. Examples include blood, pigmented ink, and paint. Colloidal sols can change their viscosity quickly if they...
