Quantico FBI validation study of Martz's EDTA detection methodology (Defense 1269-A, 1269-B)

The FBI's Quantico laboratory validation study of Agent Martz's EDTA detection methodology, including chromatograms from discovery pages 8419 and 8422 (Defense 1269-A and 1269-B). Blasier used the study to challenge Martz, who acknowledged working with Quantico on method development but said the study concerned extraction efficiency. The average extraction rate was approximately 93%.
