| titleOfInvention | Point discharge micro-plasma atomic emission spectrum analysis device in argon-hydrogen flame |
| abstract | A point discharge micro-plasma atomic emission spectrum analysis device in argon-hydrogen flame is characterized in that sample steam containing elements to be detected and protective gas respectively enter an atomic emission spectrum excitation source (point discharge micro-plasma in argon-hydrogen flame), and generated atomic emission spectrum signals are detected by a spectrum detector. The excitation source consists of a point discharge part and an argon-hydrogen flame part which are coaxially and vertically arranged in series: the point discharge part is a pair of point electrodes symmetrically arranged at two sides of the ceramic fixed seat, and a spectrum detection window is arranged at the side surface; the argon-hydrogen flame part is: the outer quartz tube is fixed on the base circle, the inner quartz tube and the outer quartz tube are coaxially arranged, the upper portion of the inner quartz tube is large, the lower portion of the inner quartz tube is small, the lower portion of the inner quartz tube is arranged on a center hole of the base, an opening at the bottom is used as a working carrier gas and sample steam inlet, and a protective gas inlet is arranged on the outer quartz tube. The invention has the characteristics of high atomization/excitation efficiency, high sensitivity, strong anti-interference capability (small interference between sample moisture and a matrix), good stability, low power consumption and the like. |
