Gas chromatograph for analysis of alcohol content (detection) in blood
With the implementation of the new Traffic Law, the detection of blood alcohol content in motorists is becoming more common. The legal and quantitative determination of blood alcohol content in headspace gas chromatography is the only means of judicial identification. The special instrument developed by our company is equipped with a real headspace sampler, omitting the complicated pre-processing process, high analysis efficiency, advanced detection method, reasonable instrument configuration, accurate detection and convenient operation. Suitable for all levels of public security departments and hospitals, judicial identification centers.
Instrument analysis range:
Qualitative analysis of blood, urine, ethanol, methanol, n-propanol, acetaldehyde, acetone, isopropanol, n-butanol, isoamyl alcohol and quantitative analysis of ethanol, methanol and n-propanol. The detection of alcohol content in blood is in accordance with the analytical requirements and analytical conditions specified in the public safety industry standard GA/T842-2009 of the People's Republic of China, which can quickly and accurately analyze the alcohol content in human blood. It can meet the needs of the traffic police judicial department across the country. Judicial standard Judicial blood determination of ethanol SF/Z JD0107001-2010
main feature:
1. The first in-line gas-carrying gas protection function (automatic power-off and alarm) in the machine, to protect the column and TCD tungsten wire from damage.
2. Adopting new humanized and dual CPU design, the temperature control accuracy is higher than +0.1 °C, with excellent reliability and anti-interference ability, and has the function of extreme temperature overload protection.
3. The liquid crystal display has functions such as adjustable background, and the display content is more abundant and intuitive. The keyboard sets various operating parameters and has a power outage
Protection function.
4. With a wide range of fault self-diagnosis function, it can help users to easily determine the fault location.
5. Has a fifth-order temperature programming function. The intelligent rear door opening system is equipped with a more reasonable inlet and outlet air duct design, which makes the column chamber cool down very quickly (for example, at other room temperature at 280 ° C, the column temperature is reduced from 280 ° C to 50 ° C and stabilized. minute).
6. The machine is basically configured as a dual hydrogen flame detector, which can be configured as a single FID amplifier or a dual FID amplifier. In addition, a large expansion space is reserved, and TCD, FPD, NPD, ECD detectors, gas injectors, reformers, etc. can be selected at any time. The host can be equipped with four detectors at the same time, and can be individually temperature controlled to achieve multi-purpose use.
7. Has six independent temperature control areas. Each vaporization chamber, detector and amplifier are modular in design. Installation and replacement is very convenient.
8. The machine can be installed with **capillary column, large diameter capillary column and packed column. The columns are easy and reliable to install.
Among them ** capillary column special vaporization chamber has a split / splitless, diaphragm purge and tail blow system.
