Application of Gas Chromatography in Blood Alcohol Detection
Posted on

The GC7980F-specific alcohol detection gas chromatograph produced by Zhengzhou Zeming Technology Co., Ltd. is a specially designed device according to the latest design and research and development of the national standard and the relevant standards promulgated by the Ministry of Public Security of the People's Republic of China and the Ministry of People's Procurement of the People's Republic of China. This model is dedicated to the GC7980F type. The blood alcohol detection gas chromatograph and instrument configuration can not only meet the technical investigation requirements of traffic policemen and policemen across the country, but also greatly increase the risk to the people’s life and safety caused by thorough investigation of the driver’s drunk driving vehicle. Quick check.

Therefore, in order to better serve the people in better safeguarding people’s life safety, and in order to coordinate with the country’s safety on the existence of drunk driving in the existing society, our company’s technical research and development team has developed and developed specifically to meet the needs of the Ministry of Public Security. The technical requirements of the judicial department standardize the alcohol content detection equipment (GC7980F blood alcohol content detection chromatograph), and better solve the life safety brought by the drunk driving vehicles to the people.


Our GC7980F blood alcohol detection gas chromatography equipment has passed the acceptance of the Judicial Identification Center of the Ministry of Justice and has been widely used and promoted in the national forensic examination center, public security, traffic police department, and hospital inspection department.

GC7980F instrument configuration: 1. GC-7980F-type gas chromatograph host 2. FID hydrogen flame detector 3. (Automatic, ZM-8A fully automatic) Headspace Sampler 4. Blood alcohol chromatography column 5. Nitrogen, Hydrogen, air source (full automatic) Gas purity 99.999% 6. Data processing system (computer, printer, chromatographic workstation) (A), GC7980F instrument Technical features: Gas chromatography analyzer (GC-7980F type) Automatic intelligent blood alcohol The dedicated GC analyzer (GC-7980F type) adopts large-screen LCD Chinese display. The operation is intuitive. The instrument has functions such as self-diagnosis, power-off protection, file storage and recall, and 8-step temperature programming. With a separate vertical heated capillary injection system, the influence of the vaporization chamber on the column chamber is minimized, and the adaptability to various syringes is improved. The new FID has a high sensitivity and facilitates the handling of nozzles and ion collectors. There are six independent temperature control zones, and each vaporization chamber, detector, and amplifier are designed with modules. It is easy to install and replace. Column column capacity, can install capillary and packed column at the same time, with independent three sampler. (B), GC7980F temperature control index: ※ temperature control area: column box, sampler, detector ※ temperature range: 5 °C ~ 450 °C on the room temperature (incremental 1 °C) ※ temperature control accuracy: better than ± 0.1°C ※Program temperature increase: Fifth-order rate 0.1°C to 40°C/min (increment 0.1°C)

Detector Index Sensitivity Drift Linear Hydrogen Flame FID M1 <1 × 10-12 g/s (n-hexadecane) <0.3mv/0.5h >107
