Beijing Huasheng Spectrum Instrument Co., Ltd. has developed a specialized instrument designed for efficient and accurate detection of blood alcohol content. This advanced device is equipped with a real headspace sampler, which eliminates the need for complex pre-processing steps. The system offers high analysis efficiency, advanced detection methods, and a well-balanced configuration that ensures accuracy and ease of use.

This instrument is ideal for law enforcement agencies, hospitals, and forensic laboratories. With the implementation of the new Traffic Law, the demand for reliable blood alcohol testing has increased significantly. Headspace gas chromatography remains the only legally recognized method for quantitative determination of alcohol in blood, making this instrument an essential tool for judicial identification across the country.

Instrument Analysis Range:

The device supports both qualitative and quantitative analysis of substances such as blood, urine, ethanol, methanol, n-propanol, acetaldehyde, acetone, isopropanol, n-butanol, and isoamyl alcohol. It meets the requirements outlined in the public safety industry standard GA/T842-2009 of the People's Republic of China, ensuring rapid and precise measurement of alcohol levels in human blood. This makes it highly suitable for traffic police departments nationwide.

Instrument Configuration:

• Gas Chromatograph
• FID + packed column injection system + capillary injection system
• Automatic headspace samplers: HS-12A and HS-20A
• Special columns, sealing pliers, sample preparation accessories, and 100 sets of top empty bottles, caps, and mats
• Chromatography workstation
• High-purity nitrogen, hydrogen, and air generators
• Internal standard
• Computer printer

Our company provides free installation, commissioning, and professional training for laboratory staff, offering a complete "turnkey" solution. The instrument comes with a one-year warranty and lifelong maintenance support.

Main Features:

• Microcomputer-controlled operation with full keyboard input and a 32-bit digital display
