DEVICES FOR SAMPLING AND CONFINING CHEMICAL CONTAMINATIONS, ASSOCIATED TRANSPORT DEVICE AND APPLICATION TO THE TRANSPORT OF CHEMICAL SAMPLES TO A CHEMICAL ANALYSIS UNIT

摘要

The invention relates to a novel 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. The invention also relates to an associated transport device and to the use of such a device for transporting chemical contaminations to a chemical analysis unit.
