The CALLS detector is insensitive to low MW and low concentration species. Therefore, the determined by this method may be erroneously high. Another commercially available MW detector is a Multi Angle Laser Light Scattering (MALLS) photometer. It should be noted that a good chromatographic... 

As mentioned in Chap. 1, randomly hyperbranched chains are even more complicated than dendrimers. It has not been completely clear whether they are fractal objects [11, 12] and whether those previously reported M-dependent intrinsic viscosities from an on-line combination of the size exclusion chromatograph (SEC) with viscosity and multi-angle laser light scattering (MALLS) detectors actually captured its structure-property relationship [11, 13]. In the next section, we ll discuss our experimental results in detail.
