I’m in Chicago attending the Gas Chromatography course at Axion Analytical Laboratory with the giants in this field, Dr. Harold McNair and Dr. Lee Polite. Gas chromatography is the testing method used to determine blood alcohol concentration in Texas when blood is drawn from a DWI suspect. This course is 5 long days of classroom and laboratory “hands on” education in this field of science. I will definitely be ready to take on any “expert” the government tries to throw at me in trial when I finish this course!
