Light scattering laser

Laser light scattering is characterized by three aspects [Pg.389]

The high intensity of the laser source makes it possible to measure weakly scattered light and to observe very small frequency shifts. [Pg.389]

Time t becomes an important variable in the measurement The quantity we are interested in, S q, t), is a function of both the angle 0 (included in q) and time t. [Pg.389]

The correlation function as an experimental device and as a technique in the mathematical analysis of the phenomena is extensively employed. [Pg.389]

The molecular weight and its distribution have been determined by laser light scattering, employing a new apparatus for ETFE dissolution and solution clarification at high temperature diisobutyl adipate is the solvent at 240°C. The molecular weight of molten ETEE is determined by high temperature rheometry (21). [Pg.366]

Particle sizing via laser light scattering has become very popular due to its simplicity of operation (Figure 1.11). [Pg.19]

In addition to polymer standards, a number of broad distribution, water-soluble polymers can be characterized on TSK-PW columns using universal calibration. These include both fully and partially hydrolyzed PVA, PAAM, PEE, and dextran. PVA, the world s largest-volume, synthetic, water-soluble polymer, was first successfully separated on TSK-PW columns by Hashimota et al. (10). In the 1980s, the use of low-angle, laser light-scattering detection... [Pg.566]
