  • Patent number: 8592222
    Abstract: A method for analyzing molecular pollutants of a fluid. From a calibrated flow of fluid, a combination of a measurement of a total amount of molecular pollutants and a determination of chemical compositions and relative amounts of the molecular pollutants by adsorption on materials is carried out. The determination of the chemical compositions and relative amounts advantageously occur after a threshold value for the total measured amount is exceeded.
    Type: Grant

  • Patent number: 8291777
    Abstract: A method of sampling and confining chemical contaminations intended for the chemical analysis of contaminations in particulate and/or molecular form with prior adsorption by a support or trapping in a liquid. The adsorbent support or the contaminated liquid is then held in position in a closed box or sealed container having chemically inert walls. The outside of the closed box or sealed container is brought into contact with a gas at a higher pressure than the pressure inside the box or container and then the temperature inside the closed box or sealed container is regulated from an environment external to the gas.

  • Publication number: 20110293151
    Abstract: The invention concerns a new method for quantifying particulate contaminants with increased reliability and that makes it possible to detect all particulate sizes according to standard ISO 14644-9. According to the invention, blowing/suction is done on a sampled surface S?, followed by a combination of analysis through optical counting of the suctioned particulate contaminants with a unit size below a value X2 and digital computation between two digital photos taken of the surface S? before and after blowing/suction, respectively, to quantify the particulates with a unit size above a value X1.

  • Patent number: 7878078
    Abstract: A device (1) for sampling particle contaminants is described. It may be adapted to a multitude of closed enclosures and with it, contaminants and/or pollutants present in the atmosphere of the enclosure may be recovered at a surface. With this sampling method, it is possible to obtain specific information as regards their behavior. In particular, the sampling device (1) comprises a support (2) on which suitable substrates (6) may be positioned, with which samples may be collected. The device (1) is conformed so as to confine the taken samples until the site of the analysis in order to further increase the specificity of the measurement.
