The Nicomp 380 was out in the field recently for a demonstration with a major chemical company and the operator was presented with a customer-made bimodal prepared by mixing a 150 nm polystyrene latex and a 350 nm polystyrene latex together to form a bimodal particle size distribution. And once again, without any input from the operator, the Nicomp deconvolution algorithm, was able to resolve it. As can be seen, the Nicomp algorithm produced a PSD with two peaks, one at 173 nm and one at 316 nm. Though the measured sizes deviate from the expected values, that is an acceptable result for such a difficult distribution.
Most other DLS instruments can at best split a 4:1 bimodal while the Nicomp 380 can split a 2:1.
