Research based on the specialities of plasma glow about the system of detecting the toxicants in food
This paper puts forward a new detecting method of toxicants in food. The research which is made by gasifying the toxicants in food to generate different specialties of plasma glow with low temperature, meets the requirement of detecting the toxicants in food fast and accurately. It analyzes qualitatively the relationship between the generation of toxicant glow and the distance, temperature and air pressure between the two poles, and the features of the lower area of cathode through introducing general principles to form plasma with low temperature and a design of a series of vacuum discharging experiments with direct current, which lays a foundation for glow chroma research in the future.
