The round robin will focus on the analysis of powder diffraction data specifically for the derivation of quantitative phase abundance. The additional methods used will be at the discretion of the participant. The samples used in the study will consist of mixtures of major and minor components covering a wide range of analytical complexity. However, since the success of the round robin will depend on the number of results returned, full participation is encouraged. Unprepared samples Samples supplied by the CPD are representative of bulk, but may need additional preparation.
Participant prepares samples for data collection and analysis.
Since the purpose of the round robin is to assess the methods of quantification, and not identification, the identity of each of the component phases will be supplied. For those participants using Rietveld based methods for the analysis, full structural information for each of the phases will also be supplied. Participants will be asked to return the results using standard reporting forms. This should minimize the number of errors likely to occur during transcription of the data.
