Principle: Use flow to create countable scattering peaks from colloidal particles, while simultaneously monitoring the background scattering due to co-existing polymers
1. Good data from a classically intractable case of high particulate contamination: a full Zimm plot determination of a polymer (PVP) coexisting with a colloid (2 mm latex spheres) (R. Schimanowski; R. Strelitzki; D. A. Mullin; W. F. Reed, Macromolecules 1999, 32, 7055-7063).
Left: Raw data for a mixture of PVP and 2 mm latex spheres at a concentration of 5120 particles/ml. Right: Zimm plot resulting from the data from left.
2. HTDLS on a Biological Test System: co-existing E. Coli and PVP polymers in solution (R. Schimanowski; R. Strelitzki; D. A. Mullin; W. F. Reed, Macromolecules 1999, 32, 7055-7063).
100 second wide swaths of raw data at different times for growing E. coli at 38°C for the 90° detector. The insets show the count rate F vs. time for these data and scattering recovered from the PVP.
