1.9 Analyzing Stored Data
In the Analyze Stored Data mode, it is not necessary to have an instrument
connected. Vision will apply your previously configured Operations Method to
the samples selected and predict the constituents. The results are displayed in
the lower window. Results for the library will report in the ID Result and Qual
Result.
Routine Analysis can be used to analyze samples in real time or to analyze
sample spectra that were previously acquired and stored. This exercise will
direct you in analyzing previously collected spectra.
