Collection involves taking a sample of the subjects blood and storing it until testing is available.  The machine used is a chromatograph.   The printout is a chromatogram, which shows what the results are.  The analyst will then interpret the results, and come to a conclusion about the blood alcohol concentration.  Jonathan was trained on Gas Chromatography a Axion Labs in Chicago, the premiere training facility for Chromatography in the Nation.
