**Technical Details of the Special Instrument Developed by Beijing Huasheng Spectrum Instrument Co., Ltd.**
The special instrument developed by Beijing Huasheng Spectrum Instrument Co., Ltd. is designed with a real headspace sampling system, eliminating the need for complex pre-processing steps. This makes it highly efficient, accurate, and user-friendly. The advanced detection method, combined with a well-structured configuration, ensures reliable performance in various applications. It is widely used in public security departments, hospitals, and judicial identification centers.
With the implementation of the new traffic law, the detection of blood alcohol content has become increasingly common. Head-space gas chromatography is the only legal and quantitative method for determining blood alcohol levels in forensic analysis. Our specialized instrument is equipped with a real headspace sampler, allowing for quick and accurate analysis without complicated preparation processes.
**Instrument Analysis Range:**
This instrument is capable of both qualitative and quantitative analysis of substances such as blood, urine, ethanol, methanol, n-propanol, acetaldehyde, acetone, isopropanol, n-butanol, and isoamyl alcohol. Specifically, it can accurately detect ethanol content in blood according to the requirements outlined in the Chinese public safety industry standard GA/T 842-2009. This ensures that it meets the needs of traffic police departments nationwide.
**Instrument Configuration:**
1. Gas Chromatograph
2. FID + packed column injection system + capillary injection system
3. Automatic headspace samplers: HS-12A, fully automatic HS-20A
4. Special columns, sealing pliers, sample preparation accessories, and 100 sets of top empty bottles, covers, and mats
5. Chromatography workstation
6. High-purity nitrogen, hydrogen, and air generators
7. Internal standard
8. Computer and printer
