Abstract
In one general aspect, a spectroscopic method is disclosed. This method includes acquiring a plurality of separate spectral measurements at different locations on a sample and evaluating results of the measurements based on one or more predetermined test criteria. Information from measurements made at the different locations is categorized based on results of the step of evaluating, and results are reported that include information from both the step of acquiring and the step of categorizing.

A spectroscopic method, including:
- acquiring a plurality of separate spectral measurements at different locations on a sample,
- evaluating results of the measurements based on one or more predetermined test criteria,
- categorizing information from measurements made at the different locations based on results of the step of evaluating, and
- reporting results that include information from both the step of acquiring and the step of categorizing.
A spectroscopic apparatus for monitoring heterogeneity of a sample, comprising:
- a sampling detector operative to acquire sampled spectroscopic measurements distributed over a range of different locations in a sample,
- a sequencer operative to cause the same sampling detector to successively acquire samples for each of a plurality of locations in the sample, and
- a spectral processor operative to derive from the sampled spectroscopic measurements a statistical measure of chemical heterogeneity.
A spectroscopic apparatus for monitoring heterogeneity of a sample, comprising:
- means for acquiring sampled spectroscopic measurements distributed over a range of different locations in a sample,
- means for causing the sampling detector to successively acquire samples for each of a plurality of locations in the sample, and
