Accurate measurement of volatile substances and blood alcohol concentration (BAC) is a critical component of forensic toxicology, especially in impaired-driving investigations. While breath testing provides rapid roadside screening, laboratory analysis of biological specimens provides the analytical specificity needed for definitive BAC determination. Headspace gas chromatography (HS-GC) with flame ionization detection (FID) remains the most widely used approach to reliably measure ethanol and other volatile substances in the laboratory. Shimadzu offers innovative GC solutions designed to streamline volatile analysis while delivering the precision, reproducibility, and confidence forensic laboratories demand.
Analytical Techniques: GC, GC-MS
Blood alcohol analysis by GC-FID and GC-FID-MS has long been a trusted approach in forensic laboratories. However, increasing case volumes and time-consuming manual preparation steps can contribute to testing backlogs. This application demonstrates the use of a robotic autosampler to automate sample preparation for blood alcohol analysis, delivering excellent reproducibility and linearity while helping streamline laboratory workflows.
Determination of blood alcohol content (BAC) has been a standard analytical method in criminal labs for many years. The typical instrument configuration consists of a static headspace instrument for sample introduction, followed by gas chromatography (GC) with two dissimilar capillary columns for separation, and two Flame Ionization Detectors (FIDs) for detection and quantitation. Two sets of data are obtained simultaneously, and the quantitative results from the two FIDs are compared for confirmation of the reported BAC levels.
While headspace GC-FID analysis has long been a reliable approach to determine blood alcohol content (BAC), ensuring your workflow is operating at peak performance remains of great importance. This application explores how the GC parameters for dual-column analysis using the GC-2010 Plus or Nexis GC-2030 with the HS-20 loop sampler can be optimized for dual FID detection. Even minor changes can resolve common chromatographic distortions associated with conventional parameters.
Headspace GC-FID is a common technique used for the analysis of volatile compounds, including various alcohols. This application demonstrates an optimized GC-2010 Plus and HS-10 workflow that delivers fast BAC determination, reduced helium consumption, and excellent linearity. At times when helium prices continue rise, this workflow provides consistent results while improving laboratory efficiency.
Every day in America, 29 people die in drunk driving accidents …according to the National Highway Traffic Safety Administration. To prevent future incidents and ensure appropriate legal action is taken, forensic laboratories must be able to effectively analyze ethanol in blood samples. One of the most widely used methods is blood alcohol testing. 2 Using blood alcohol testing, forensic toxicologists can determine the amount of alcohol that is in a person’s blood at the time the sample is taken. However, without the right instrumentation, performing this type of analysis can be time-consuming and challenging.
The GC/MS Forensic Toxicological Database contains information for the simultaneous screening of toxicological substances including drugs of abuse, psychotropic drugs, medical drugs and pesticides. Version 2 adds 1198 compounds to the previous version for a total of 2210 compounds in the database. It also includes optimized methods for headspace analysis of alcohol and volatile toxic substances such as cyanides and azides, providing total support for GC/MS toxicology analysis.
For many forensic laboratories, there is a need for a simpler, faster and more effective way to conduct analysis. These labs face the challenge of delivering accurate results for an increasing number of samples. To improve productivity and confidence in results, they need more advanced instrumentation and software solutions designed specifically for forensic analysis. Shimadzu’s Smart Forensic Database helps you easily and automatically create multiple reaction monitoring (MRM) methods for GC-MS/MS toxicological analysis.
