Methods and apparatus for introduction of sample from a flowing stream into mass spectrometers or other analyzing apparatus for analytical and process stream analysis of the sample. The apparatus generates an aerosol during the decompression of a gas, liquid or supercritical fluid stream. The aerosol's properties are dependent upon mass flow, pressure, temperature, solubility of sample, and the physical dimensions of the aerosol generating device. Upon aerosol generation, a less volatile sample in the form of condensed particles is separated from the gaseous components by accelerating the aerosol through a nozzle restrictor and utilizing momentum differences between solute particles and carrier gas molecules to obtain high solute enrichments at various particles or gas-phase detectors. The device functions primarily as an interface between a supercritical fluid chromatograph and the mass spectrometer.
