**Gas Chromatography for Forensic Identification**
The gas chromatographic test is widely used in forensic identification, especially for the determination of alcohol content in blood. With the implementation of new traffic laws, the detection of blood alcohol content has become more common. The legal and quantitative analysis of blood alcohol using headspace gas chromatography is the only accepted method for judicial identification.
Our company has developed a specialized instrument that features a real headspace sampler, eliminating the need for complicated pre-processing steps. This ensures high efficiency, advanced detection methods, and accurate results. It is ideal for use by public security departments, hospitals, and forensic identification centers across the country.
**Scope of Analysis**
This system supports both qualitative and quantitative analysis of various substances including blood, urine, ethanol, methanol, n-propanol, acetaldehyde, acetone, isopropanol, n-butanol, and isoamyl alcohol. Specifically, it can accurately measure ethanol, methanol, and n-propanol levels in blood samples in accordance with the requirements specified in the Chinese public safety standard GA/T 842-2009. This makes it suitable for meeting the needs of traffic police and judicial departments nationwide.
