Abstract
The combined employment of the SPLITT (split-flow thin) cell — a relatively new system for fast, continuous binary separation — and of gravitational field-flow fractionation (GrFFF) — a fractionation technique suitable for micron particle size distribution determination — was investigated for starch separation and characterization. Emphasis is placed on the main advantages of both techniques: operating under gentle earth gravity field, low cost and ease of maintenance. The reproducibility of GrFFF is demonstrated. Both the SPLITT separation and GrFFF fractionation results were checked by optical microscopy. Application examples of typical starch fractionation experiments are reported and discussed.
