摘要
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.
