Embodiment Construction
[0075] The sampling sleeve 1 according to the present invention includes a cylindrical housing 10, 10', 10", and two covers 11 arranged on each side or each end 100, 101 of the housing 10, 10', 10" And 12 and the adsorbent 13 placed inside the housing 10, 10', 10". The housing 10, 10', 10" can be made of amber or transparent glass. The amber glass has the advantage of protecting the adsorbent 13 and light-absorbing photosensitive molecules from light. Glass generally also has the advantages of being an inert material and having excellent thermal conductivity, which can reduce thermal desorption time. The casing 10, 10', 10" of the sampling sleeve 1 is preferably cylindrical, but can also have other cross-sections, such as square, hexagonal, elliptical, etc. cross-sections depending on the application. The adsorbent 13 is, for example, readily available , A solid polymer for sole purpose or a special adsorbent that allows universal capture of any type of pollutants. Covers 11 a...

The invention relates to a method for sampling and extracting pollutants in a fluid, a sampling cartridge, sampling and extraction devices using the method. The present invention relates simultaneously to a sampling cartridge (1), a sampling device (2, 3), an extraction device (4) and a sampling and extraction device (5) which enable a safe measurement without contamination of the adsorbent eitherbefore or after the sampling. Thus the sampling cartridge (1) according to the invention comprises an envelope (10) made of inert material in which an adsorbent material (13) is placed, sealed in a leaktight manner by two caps (11, 12) located at the two ends (100, 101) of the envelope (10), each cap (11, 12) having an opening (111, 121) which is closed by a seal (110, 120) formed of a silicone film and a barrier layer made of aluminium that withstands the high temperatures necessary for the thermal desorption technique, namely between 250 DEG C and 350 DEGC. The cartridge (1) is packaged under inert gas and its ends (100, 101) comprise at least one end piece to be sealed (102) for a sealed cap (11, 12), and one universal end piece (105) for a sealed, screwed or clip-fastened cap (11, 12).
Description
Technical field [0001] The present invention relates to the sampling of pollutants in fluids such as air or water. The pollutant sampling is carried out according to specific standards described in the literature. [0002] The measurement of indoor air quality is usually applied to: [0003] -Residential; [0004] -Places open to the public; [0005] -office. [0006] The measurement of the quality of flowing water involves water distributed in houses and water in all public places, as well as surface water in rivers and well water. [0007] These application examples are of course not restrictive. [0008] The present invention therefore relates to methods for sampling and extracting contaminants in fluids, sampling sleeves for implementing the methods, and various sampling and extraction devices. Background technique [0009] The extraction of pollutants in the air has been carried out actively or passively so far. Pollutants refer to, for example, volatile organic compounds (COV). Vol...
