Method and apparatus for analyzing sample solutions

摘要

A system and process for analyzing a liquid sample is disclosed which includes an ultrasonic nebulizer capable of vibrating at a frequency between about 50 Khz and 760 Khz for converting the liquid sample to a liquid aerosol. The liquid aerosol is heated at a pressure of at least atmospheric pressure to evaporate solvent in the aerosol and to form a solid aerosol. The solid aerosol is separated from the evaporate solvent and the solid aerosol is directed into an electron impact ionizer and a mass spectrometer where it is analyzed.
