Summary of returns showing the type of microabsorption correction applied during the analysis of data collected by participants and supplied by the CPD for sample 1g. The number after each entry represents the number of analyses (including replicates) in each group. This figure more accurately represents the range of data analysed since many participants conducted analyses both with and without microabsorption correction. For the Brindley correction model, the assumed particle sizes (µm) for the three phases, corundum, fluorite and zincite, are respectively: Size A: 0.5, 0.5, 0.5; Size B: 5, 5, 5; Size C: 8.4, 13, 11.6; Size D: 10, 10, 10; Size E: 18, 3.6, 1.4; Size F: 28, 3.6, 1.4. |
