Description

[0002] Inductively coupled plasma mass spectrometry is a highly sensitive and selective analytical technique that uses an inductively coupled plasma as an ionization source to ionize the elements in a sample. After these ions enter a mass spectrometer, through mass spectrometry analysis, ions of each element are measured and detected based on the mass / charge ratio, and it is widely used in the fields of materials, chemical engineering, biology, medicine, metallurgy, petroleum, environment, etc.

[0003] During the analysis process, the main function of the sample nebulizer is to convert a liquid sample (usually a sample dissolved in water or an organic solvent) into tiny mist-like particles or droplets, and these particles will be dried and ionized before entering the inductively coupled plasma. When precipitates, depositions, or incompletely dissolved sample components during the sample preparation process form solid particles or precipitates in the sample solution, they will block the nozzle or internal structure of the nebulizer, affecting the accuracy of the final analysis results.
