  • Integrated collection and vaporization particle chemistry monitoring
    Patent number: 5983732
    Abstract: An integrated collection and vaporization cell apparatus has a collector and vaporizer cell for collecting airborne particles from sample gas on a collector strip in the cell and a power source connected to the strip for rapidly heating the strip and converting the particles to vapors for analysis without need of removing the strip from the cell. A sample gas director connected to the cell directs sample gas and particles to the collector strip. Particles are collected on the strip by impaction. Rapid heating of the strip vaporizes the particles. A carrier gas flowed into the cell through the director and directly into the cell through a port directs the vapors from the cell to an analyzer port. A measurer connected to the analyzer port measures the amount of vapors and elemental constituents obtained from vaporization of the particles. A humidifier is provided to increase particle collection efficiency.
