Abstract: In a system for analyzing the elemental or molecular composition of a sample wherein the sample components are excited through collision with an active metastable gaseous species, the excited sample components emitting a characteristic wavelength of light which may be detected, the system including a microwave cavity (16) through which the gaseous species flows and a microwave source (17) coupled to the cavity, the microwave discharge exciting the gaseous species, an improved liquid sample introduction system (30) which causes complete vaporization and disassociation of the sample. The sample is preferably aspirated directly into the microwave discharge within which the active gas is generated. A sample and gas injection probe (33 and 34) is also disclosed.
