    Abstract

    Flame photometric analysis technology has been proven to be a rapid and sensitive method for sulfur and phosphorus detection.It has been widely used in enviro nmental inspections,pesticide detection,industrial and agricultural production.By improving the design of the traditional flame photometric detector,using grating and CCD sensor array as a photoelectric conversion device,the types of compounds that can be detected were expanded.Instead of a single point of characteristic spectral lines,full spectral information has been used for qualitative and quantitative analysis of H2S,PH3,NH3,AsH3 and Cl2.Combined with chemometric method,flame photometric analysis technology is expected to become an alternative fast,real-time on-site detection technology to simultaneously detect multiple toxic and harmful gases.
