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
