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.

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… Voir plus

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… Voir plus

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.

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… Voir plus
