Excess Rayleigh scattering

Equation (7.36) is known as the Debye plot. Figure 7.11a and Figure 7.11b show the excess Rayleigh scattering intensities of polyacrylamide from MALLSP (multi angle laser light scattering photometer) and LALLSP, respectively. [Pg.433]

Local Properties. Local properties are values such as detector response, molecular weight, or polymer size at a particular retention volume of a size-exclusion chromatogram. They are denoted by the subscript i. The excess Rayleigh scattering, Rei, at each retention volume Vi of an SEC is related to the concentration at each retention volume, Ci, and angle, 6, by...

Consider the measurement of the excess Rayleigh scattering in a dilute polymer solution. The expression for the scattering of a group of independent particles within the limit of infinite dilution is ... [Pg.69]

R( The excess Rayleigh scattering factor defined as the Rayleigh ratio of the solution or single particle event from which is subtracted the Rayleigh ratio of the carrier fluid along with any other background contribntions. [Pg.6]
