Determined by SEC using a Viscotek TDA300 detector which collects right-angle laser light scattering, viscosity, and RI information... 

In the second detector design, multisheath flow detector, the capillaries are illuminated with a line-focused laser beam. Huorescence is collected at right angles and imaged onto a CCD camera. The use of the CCD camera ensures that aU capillaries are monitored simultaneously. To eliminate light scattering, the capillary array is inserted into a...
