'As a lawyer, you can’t properly defend a DUI alcohol or drug case unless you have an understanding of the science associated with the analysis of the evidence. - Manuel J. Barba

Attorney Manuel J. Barba completed the required courses for the ACS-CHAL Forensic Lawyer Scientist Designation at: Axion Laboratories, Inc. in Chicago, IL.

The first course: “Introduction to Forensic Chromatography” focused on ethanol analysis using Head Space Gas Chromatography with a Flame Ionization Detector. This is the process used by most government crime labs in analyzing a driver’s blood sample to try to convict someone of driving under the influence.

The second course: “Forensic Drug Analysis: Solid Drug Dose Testing” involved the instrumental analysis of solid drugs in their pre-consumption form using Gas Chromatography coupled with a Mass Spectrometer. The course participant learns scientific methods to answer questions such as: Is that white powder cocaine? What is the concentration of the heroin seized? Is that tablet legal drugs or illegal drugs? Is this a counterfeit or pharmaceutical drug? The course focused on all drugs of potential abuse including illicit drugs, marijuana, pharmaceuticals, synthetic canabinoids, and synthetic cathinones. The course teaches participants to understand how drug testing in pre-consumption form (solid drug dose) is conducted for nearly all drugs of abuse, sources of uncertainty (misidentification) of the qualitative measure, sources of uncertainty (wrong concentration or weight) of the quantitative measure, representative sampling, validation of methods, bench work, and federal analog act prosecution. Attendees used reagents (colormetric tests), GC-MS, GC-FID, and FTIR instruments with samples containing unknowns.

The third course: “Forensic Principles of DUID” focused on the analysis of biological fluids (blood, urine, hair, oral fluid) for drugs of abuse. As the name implies, it focuses on DUID from the alleged motorist’s point of view. The course included instrumental analysis on the qualitative and quantitative analysis, in addition to pharmacology including pharmacokinetics and pharmacodynamics. The course involved hands-on use of instruments and actual processing of biological samples.

The fourth course: “Advanced Forensic Chromatography” focused on more advanced topics related to Head Space Gas Chromatography including troubleshooting problems that arise in the chromatography process.    

After completing all four courses, Attorney Barba had to pass a rigorous written examination to be eligible for the ACS-CHAL Forensic Lawyer-Scientist Designation. There are currently only four lawyers throughout the State of California that have received the ACS-CHAL Forensic Lawyer-Scientist Designation.
