To fully comprehend the processes of chemical testing, your DUI attorney should understand gas chromatography – mass spectrometry. Gas chromatography mass spectrometry (hereinafter GCMS) is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample. GC-MS has been widely heralded as a “gold standard” for forensic substance identification because it is used to perform a specific test.
Ohio Administrative Code 3701-53-03(A) sets forth the techniques and methods for determining the concentration of alcohol in blood, urine and other bodily substances. Pursuant to that rule, Ohio allows for testing including gas chromatography and enzyme assays. The GCMS instrument is made up of two parts. The gas chromatography (GC) portion separates the chemical mixture into pulses of pure chemicals and the mass spectrometer (MS) identifies and quantifies the chemicals. The GC separates chemicals based on their volatility, or ease with which they evaporate into a gas. It is similar to a running race where a group of people begin at the starting line, but as the race proceeds, the runners separate based on their speed. The chemicals in the mixture separate based on their volatility. In general, small molecules travel more quickly than larger molecules. The MS is used to identify chemicals based on their structure.
In order to successfully defend a blood test case, a DUI defense lawyer must be familiar with Ohio’s DUI law (O.R.C. 4511.19) and the Ohio Administrative Code sections which apply to the collection, storing, transporting and testing of the whole blood, blood plasma and/or blood serum specimen. Amphetamine, cocaine, heroine, Marijuana, Methamphetamine, Phencyclidine and L.S.D. are specifically mentioned in Ohio’s DUI/OVI statute as illegal controlled substances. The law states how much of each substance must be detected in a chemical test of urine, whole blood, blood plasma, and/or blood serum in order to sustain a charge. A blood test is seen as the most accurate and reliable method of testing but is the most invasive. The blood test is increasingly favored by law enforcement officers because it allows them to expand the parameters of their suspicion to include illicit and prescription drugs. Sometimes the blood test will be requested after a breath test produces a result under the .08% BAC limit. If this is the case, your attorney should employ more traditional factual defenses such as a lack of probable cause to suspect drug use before leaping to a more scientific challenge to the collection, storage, transporting or testing of the blood sample. If the facts support a blood test then your attorney must hold the State to its proof.
