The frequent occurrence of drunk driving and the increasing number of traffic accidents caused by drunk driving have made it an important and arduous task for traffic police and judicial departments in various regions to quickly, accurately, and stably analyze the alcohol content in the blood of drunk driving drivers. Our company producesGC9890 gas chromatographUsed in conjunction with the fully automatic headspace sampler HS-9A HS-16A, the detection of alcohol content in blood follows the analysis requirements and conditions specified in the public safety industry standard GA/T842-2009 of the People's Republic of China. It can quickly and accurately analyze the alcohol content in human blood, meeting the needs of traffic police and judicial departments across the country.
GC9890 typeFully automatic intelligent headspace chromatography combined instrument for blood alcohol detectionIt is developed and produced by our company, Kemei Ao, in accordance with the industry standard GA/T842-2009 of the Ministry of Public Security of the People's Republic of China. In order to cooperate with the national traffic police, public security system, judicial appraisal (institute) centers, and hospitals in the technical characteristics of high precision and fast work efficiency for the detection equipment of blood alcohol (ethanol) content in drivers who drive under the influence of alcohol, our company has specially launched a domestic product*Fully automatic intelligent blood alcohol dedicated gas chromatography analysis (GC9890 type).Fully automated operation, continuous analysis, and unmanned operation have been achieved, truly realizing unmanned intelligent operation processes.
Applied to judicial appraisal units in Guangdong, Guangxi, Quanzhou, Xiamen, Fuzhou, Henan, Anhui, Sichuan, Gansu, Shandong and other places across the country, as well as traffic police brigades

（1） Technical characteristics of the instrument:Gas chromatography analyzer(GC9890 specialized alcohol detector)
Fully automatic intelligent blood alcohol dedicated gas chromatography analyzer(GC-9890 type)Adopting the technology of Hewlett Packard Company in the United States, the instrument has intuitive full keyboard settings and operation. It has functions such as self diagnosis, power-off protection, file storage and retrieval, program temperature rise, etc. Split/non split capillary injection system, FID uses HP technology logarithmic amplifier,FIDIt has high sensitivity and can be conveniently used for nozzle loading, unloading, and cleaning. It has six independent temperature control zones, and each vaporization chamber, detector, and amplifier adopts modular design, making installation and replacement convenient and simple. The chromatographic column box has a large capacity and can accommodate both capillary and packed columns simultaneously. Each detector data channel has analog signal value output.
（2） Temperature control indicators:
※Temperature controlled area: chromatographic column box, sampler, detector
※Temperature control range: 5 ℃ to 450 ℃ at room temperature (incremental 1 ℃)
※Temperature control accuracy: better than ± 0.1 ℃
※Program heating: Third order rate 0.1 ℃~70 ℃/min (incremental 0.1 ℃)

Instrument features:
The headspace sampler controls the chromatograph to achieve automatic operation, continuous analysis, unmanned operation, and maximize work efficiency.
After each injection is completed, the system automatically uses inert gas to blow the sampling pipeline and quantitative ring to prevent cross contamination.
The inert injection channel from the injection needle to the transfer pipeline is a standard configuration of HS-16A. Obtained complete inertness of the injection system.
From the sample to the instrument inlet, the entire system is heated to eliminate system cold spots, reduce sample peak broadening, and increase separation efficiency. Make sample analysis more accurate.
