With an increase in OUI drugs arrests in Massachusetts, Massachusetts OUI Lawyers can expect to see an increase in OUI drugs arrests. In serious case, there is likely to be forensic testing of blood for drugs. In OUI alcohol cases, typically a suspect will be asked to take a breath test. In case involving, injuries to the operator believe to be under the influence, forensic testing of the blood may be requested in cases involving serious bodily injury or death. Recently, I attended a seminar called Serious Science sponsored by the National College of DUI Defense. This seminar featured a first hand view of the Science with a visit to the University of Texas Lab at its Arlington campus. This was an excellent event run by a Andrew Mischlove, Joe St. Louis and Virginia Landry, lawyers I have known for many years. They were assisted by two other outstanding lawyers who work with the Gerry Spence Trial College Kimberly Benjamin from Missouri and Franciso Durate from Washington State.
Gas Chromatography separates the elements of a compound for analysis by a forensic scientist. What happens is the machine takes an element and transforms it into the gas phase for analysis. The machine then determines what type of substance is being analyzed by the retention time. As part of our work in the lab, we created standards; these standards are used so that there is a known solution that is put into the machine that comes out at a specific time. The unknown standard is then compared to the known standard that are prepared in the laboratory.
Liquid Chromatography is also another type of separation analysis where the compounds are turned into a liquid instead of a gas. Liquid Chromatography allows for greater depth of analysis as some compounds cannot be transformed into a gas phase; the use of liquid chromatography is the most accurate way to detect drugs in the blood steam.
