    Inventors: Stephen T. Ferguson, Ilias G. Kavouras, Jack M. Wolfson, Petros Koutrakis
  • Method and apparatus to measure particulate matter in gas
    Patent number: 5571945
    Abstract: Apparatus for measuring the amount of particulate matter in a gas having a gas supply, a first particulate matter collector downstream of the gas supply and in gaseous communication with the gas supply, and a second particulate matter collector downstream of the gas supply and in gaseous communication with the gas supply. Gas from the gas supply to the second particular matter collector is passed through a particle remover to remove particulate matter prior to contact of gas from the gas supply with the second particulate matter collector. A pressure sensor is provided to measure differential pressure between the first particulate matter collector and the second particulate matter collector, and at least one pump to cause gas to pass from the gas supply to the first particulate matter collector and the second particulate matter collector.
    Type: Grant
    Filed: March 13, 1995
    Date of Patent: November 5, 1996
    Inventors: Petros Koutrakis, Peng-Yau Wang, Jack M. Wolfson, Constantinos Sioutas
  • Denuder for gas sampling
    Patent number: 5302191
    Abstract: A denuder for collection of gases, consisting of a plurality of generally parallel elongated tubes having a surface formed from an inert non-metallic material, said tubes being configured and arranged to allow recovery of gaseous material collected on each said surface.
    Type: Grant
    Filed: September 1, 1992
    Date of Patent: April 12, 1994
    Assignee: President and Fellows of Harvard College
    Inventors: Petros Koutrakis, Stephen T. Ferguson, Jack M. Wolfson
  • Ozone monitors
    Patent number: 5185129
    Abstract: An ozone monitor including an ozone reactive surface, held within a container, which is adapted to specifically react with ozone. The surface is also adapted to fail to react with nitrogen dioxide in an amount which affects ozone quantitation by more than 20% when the nitrogen dioxide is provided at a concentration of 76 ppb and ozone is provided at a concentration of 30 ppb within a test gas.
