Abstract
Simplified method and apparatus for connecting a liquid chromatograph, particularly of a high-performance type, directly to a mass spectrometer without using any complicated devices conventionally available, for the purpose of continuous and stable mass spectrometric measurement of a liquid sample, either liquid or solution, more commonly an effluent supplied directly from a column of the liquid chromatograph or an aliquot portion thereof extracted through a simple and ordinary splitter, or any other liquid samples prepared for the mass spectrometric analysis. Such a liquid sample is first sprayed into finely divided particles by a nebulizing means mainly consisting of a double-tubing capillary so that the sample is easily vaporized, and finally introduced into an ionizing portion of the mass spectrometer in continuous and stable manner.
