Abstract
A system and method for the automatic sampling and dilution of homogeneous particle dispersions is developed that uses a multistep parallel dilution network system for the sample and diluent and includes variable dilution capabilities. The sample and diluent are combined and allowed to mix uniformly over a predetermined conduit length. Resampling from the first dilution step and recombining with another diluent line results in a second dilution step. The number of steps determines the dilution range; the manipulation of the sample and diluent flow rates provides a variable dilution ratio at each dilution step. An exemplary embodiment reduces the concentration of a latex sample for analysis with uv-vis spectrometry. In another embodiment, the emulsion polymerization of styrene is followed in real time with turbidity measurements taken on diluted samples.
