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:

D11 at the ILL Grenoble, France

Data measured with a sample-detector distance of 34 m and an incident wavelength of 13 Angstrom and 6 Angstrom Data measured with a sample-detector distance of 8 m and an incident wavelength of 6 Angstrom Data measured with a sample-detector distance of 1.2 m and an incident wavelength of 6 Angstrom

Quokka at ANSTO, Lucas Heights, Australia

Data measured with a sample-detector distance of 20 m and an incident wavelength of 5.08 Angstrom

SANS2D at ISIS, Didcot U.K.

A sample with nominal concentration 0.5% has been measured with a sample-detector distance of 12 m. (This instrument uses a polychromatic beam in time-of-flight mode.)


Data Format

Contributors are encouraged to deposit their data using the cansas1d/1.0 XML data standard for 1-D SAS data within a ZIP or gzip archive file. A WWW form (canSAS/xmlWriter) is available to translate three-column ASCII text data into the canSAS1d/1.0 XML format.
