Blood Alcohol Analysis System

In fields such as forensic medicine and emergency care, analysis of the components in the blood is frequently performed in order to assess the cause of death or symptoms, and to evaluate criminality. The measurement of alcohol, primarily ethanol, is utilized to determine drunkenness and to separate drinking from other clinical cases. Other methods are known for easily calculating alcohol concentration from exhalation and saliva. However, gas chromatography is generally utilized because it’s a highly precise measurement method.
The Shimadzu Blood Alcohol Analysis System combines a gas chromatograph equipped with the world’s highest sensitivity detector and an electronic flow controller with a headspace sampler that keeps the sample line as short as possible, providing high sensitivity and repeatability as well as low carryover.

Example of the Analysis of Blood Alcohol

Two special-purpose columns for blood alcohol analysis are available, enabling quick analysis of target alcohols with complete separation. Performing the analysis with two columns with different polarities enables a more accurate qualitative analysis.

Example of the Analysis of 7 Components Using the SH-RtxTM-BAC Plus 2 Column (0.1 mg/mL each)

Example of the Analysis of 10 Components Using the SH-RtxTM-BAC Plus 1 Column (0.1 mg/mL each)

Example of the Analysis of Blood with the Equivalent of 8 to 160 mg/100 mL of Ethanol (EtOH) Added
