A round-robin study has been carried out to estimate the impact of the humanelement in small-angle scattering data analysis. Four corrected datasets wereprovided to participants ready for analysis. All datasets were measured onsamples containing spherical scatterers, with two datasets in dilute dispersionsand two from powders. Most of the 46 participants correctly identified thenumber of populations in the dilute dispersions, with half of the populationmean entries within 1.5% and half of the population width entries within 40%.Due to the added complexity of the structure factor, far fewer people submittedanswers on the powder datasets. For those that did, half of the entries for themeans and widths were within 44 and 86%, respectively. This round-robinexperiment highlights several causes for the discrepancies, for which solutionsare proposed. |
