The objective of the pre-amenability study is two-fold:
- To provide a qualitative of optical differences between the samples – this is to confirm that the MQi technology can consistently detect differences between samples over a range of compositions
- To provide a limited quantitative measure of data fit between MQi optical data and reference analytical data
Note that the low number of samples used in the pre-amenability study does not enable quantitative prediction of unknown samples. The pre-amenability study serves as a go/no-go metric only.
Quantitative full amenability studies are ideally performed on a set of 50 to 60 well-chosen samples with known compositions. A few additional ‘unknown’ samples may also be included for prediction of their analysis values.
The objective of an amenability study is to do a full calibration on off-line samples in order to predict:
- The expected accuracy of a final installation
- The expected predictibility for the final installation
- The analysis values of the supplied ‘unknown’ samples
