Laser light scattering detection

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...

The observations and questions raised by these workers helped stimulate the experiments which are presented here. In this work, size exclusion chromatography with low angle laser light scattering detection (SEC/LALLS) was used to probe the distribution of branching functionality in multiarm macromolecules of styrene/isoprene and styrene/buta-...

In further experiments in oxygenated solutions using pulse radiolysis techniques with low-angle laser-light scattering detection, the yields of strand breakage were measured at pH values of 7, 9.7 and 10.4. Table 2 summarises these data. 

Laser Light Scattering Detection of Microemboli. To elucidate the mechanism of platelet destruction by grafted polyacrylamide-Silastic surfaces, an optical scattering technique was developed (20) to observe and quantitate the sizes and size distributions of microaggregates in blood produced within the AV baboon shunt. Presumably, any such flowing microaggregates represent platelet microemboli. 

Laser Light Scattering Detection of Microemboli. The optical scattering technique was used to assess in vivo the thromboembolic propensity of polyacrylamide-Silastic and Silastic shunts of varying lengths. In four baboons, control measurements of the number and size distribution of throm-boemboli produced by the 35-cm proximal section of the chronically... 

Schom et al. (22) also proved that it is feasible to use HFIP with sodium trifluoroacetate, unmodified silica columns, and low-angle laser light-scattering detection for direct MW measurement of nylon 6. They also showed that spikes can be minimized in the LALLS signal by water exclusion, filtration, and a data-smoothing technique.
