Cleaning agent and cleaning method for sampling cone and interception cone of inductively coupled plasma mass spectrometer

The invention discloses a cleaning agent and a cleaning method for a sampling cone and an intercepting cone of an inductively coupled plasma mass spectrometer, and belongs to the technical field of scientific instruments. The cleaning agent is mainly composed of a complexing agent, a surfactant, a solubilizer, an antirust agent, inorganic acid and a proper amount of deionized water, and the complexing agent is an amino carboxylate substance. The metal cleaning agent provided by the invention does not use chemicals with stronger toxicity, volatile solvents and chemical reagents which easily cause corrosive damage to the cones, is common reagents in laboratories, has certain oxidation and complexing capabilities, has a better cleaning effect on surface sediments of the sampling cones and the interception cones, is simple in preparation method, low in cost and short in cleaning time, and can be widely applied to the field of cleaning of the sampling cones and the interception cones. Cleaning is thorough, seconda
