This invention discloses a method and apparatus for detecting impurity elements in organic solutions, belonging to the field of component detection technology. The apparatus includes an ICP system, a sample introduction system, and a spectroscopic analysis unit. The ICP system has a three-layer concentric rectangular tube structure, with an enlarged inner diameter and a narrowed opening in the central tube, and the inner wall coated with yttrium oxide. The outer and middle tubes form independent cooling and auxiliary gas channels. The sample introduction system includes a temperature-controlled nebulizer chamber and a three-way mixing valve. The spectroscopic analysis unit uses a two-point background correction method to process the signal. The method uses a 1.6-1.8 kW gradient power to excite and create an online micro-oxidation environment, acquires the signal, performs two-point background correction, and calculates the concentration using a matrix-matched calibration curve. This invention achieves continuous and stable plasma operation with no significant carbon buildup, and the relative standard deviation of continuous measurements is <3%, making it suitable for batch detection of various organic solutions.
