The new system can detect 157 chemical poisons for 5 minutes.


If an unknown gas suddenly "visits", how long can it be made to accurately determine whether the gas is harmful? 5 minutes! Zhuhai City CDC's "Occupational Chemical Poisoning Analysis and Detection System Research" project can "diagnose" 157 chemical poisons and complete sampling and analysis within 5 minutes, providing technology for emergency response to public health emergencies and other events. support. The project won the third prize of Zhuhai Science and Technology Achievements, filled the relevant technical gaps in China, and was the only award-winning project in the city's health system during the year, and has been applied and verified in many cities across the country.

Can characterize 157 chemical poisons at the same time

“In general, different chemical poisoning tests are performed in different ways, but our system optimizes and integrates these testing methods.” The relevant person in charge of the Municipal Center for Disease Control and Prevention said that for air samples, only one collection is required. At the same time, 157 chemical poisons can be qualitatively confirmed and quantified simultaneously, which greatly improves the speed of analysis and detection of multi-component sampling.

At the same time, the system can establish an online analytical method for rapid detection of inorganic gas poisons by mobile laboratory vehicle technology. “Including the sampling and analysis process for less than 5 minutes, the scope of application can be further extended to the field of organic gases,” the official said.

Become a scientific basis for rescue and decision-making

It is understood that the establishment of the "Research on the System of Occupational Chemical Poisoning Analysis and Detection System" will greatly improve the accuracy, detection speed and specificity of the identification of poisoning substances in chemical poisoning incidents, which can be used as a technical system support for emergency response to public health emergencies. It can also be applied to daily occupational health monitoring and evaluation. The system enables the laboratory to carry out emergency detection of occupational poisoning-related emergencies at any time, providing timely and accurate scientific evidence for the confirmation of poisoning properties, on-site emergency rescue, the formulation of health administrative department control strategies and even government decision-making.

It is reported that the results have been promoted and applied in disease prevention and control institutions and occupational disease treatment institutions in Guangdong, Hubei, Tianjin, Hainan and other provinces and cities.
