Samples

A polystyrene latex sample has been used for round robin measurements. As it is fairly monodisperse, it provides good tests for resolution. The hydrogenous polystyrene latex designated PS3 has been prepared in Uppsala (Materials Physics, Uppsala University) by Maja Hellsing.

Three samples at nominal concentrations of 0.4%, 0.1% and 0.025% designated A, B and C have been prepared in D2O with 1 mM added NaCl.

Measurements

At present (30 April 2012) the following instruments have been used for SANS measurements on the latex samples:
