Spectroscopy Europe: "Sampling Column"

I really recommend to visit the "Sampling Column" web page of  "Spectroscopy Europe Magazine", where you can find very useful articles to download and to become an expert in the theory of sampling. 
Sure we can find some good advices to get a representative sample to analyze in our instruments to improve the correlation and errors of the calibrations.
