ABSTRACT:
A method and apparatus are provided for analyzing an analyte at low concentration in a liquid sample by photoionization and mass spectrometry. An inlet system is provided for direct injection of the liquid sample using a capillary tube. The method and apparatus allow for 20 to 2000-fold improvement of the lower detection limit of an analyte in a liquid sample compared to a conventional liquid chromatography/mass spectrometer apparatus.
