Micro metal ion detecting device

The utility model discloses a micro metal ion detecting device, which is mainly used for solving the problems of high price and complex structure, or low price, low sensitivity and poor repeatability of the existing analytic instrument. The micro metal ion detecting device comprises a shading auxiliary system, a micro flame source, a sample feeding unit and a spectrum detection unit, wherein the shading auxiliary system comprises a cubic outer shell and a cubic inner shell; the micro flame source comprises a butane blast burner which is fixed on the bottom surface of the inner shell; the sample feeding unit comprises a sample feeding pipe, a surface vessel and a cone; the spectrum detection unit comprises a quartz sheet, a spectral probe and a CCD (Charge Coupled Device) spectral instrument. The micro metal ion detecting device overcomes the shortcomings of the existing detection technology; as a result, quantitative analysis of liquid-phase medium-heavy metal pollutants and field analysis of samples can be r
