SMSLS collects the scattered light simultaneously from multiple independent samples in which time dependent processes may be occurring. It has been conceived as a tool for high throughput screening in a number of contexts:
A recent prototype built by Michael Drenski. It includes 12 independent chambers, 4 of which are flow cells, and eight of which are insertable cuvettes in an index matched bath.

The relationship between the Time Dependent Static Light Scattering (TDSLS)signatures and the intra- and interparticle characteristics of the polymer population, as the solution passes from the dilute to semi-dilute regime, is sought theoretically, and measured experimentally.
