Box plot spectra

I have been working this day quite a lot with the concept of good product, and the spectrum with boxplots is a niece example to detect samples which can be contaminated or not to be good product.
 
Always in the case that the good product could be the average spectrum of N samples considered or tested that are good, we can define with all the good samples a boxplot spectra, and over-plot over it new samples and see if they are out of the limits at certain wavelengths, so this can be a clue for a contamination, a confusion in the mixture with the percentages or the components of the mixture.
