| titleOfInvention | Ion source for analysis of low volatility species in the gas phase |
| abstract | A method and apparatus that ionize vapors for their chemical analysis is described. The new ionizer improves the ionization efficiency by reducing dilution of sample molecules and improving transmission of ions to the analyzer. This is accomplished by a new flow configuration, in which a stream of clean gas focuses the ions towards the analyzer. A deflector prevents the formation of turbulent perturbation, and the ionization maintains a laminar regime without the need for additional separating walls or electrodes. The flow within the ionizer is configured so that contaminants released by the inner walls of the ionizer do not reach the ionization region. The resulting ionizer improves the ionization efficiency, and the background levels for low volatility species. This makes it ideal for the analysis of low volatility species in the gas phase. One application of this ionizer is the analysis of human breath in real time. |
