The permeated gas is transported to the detector by a stream of carrier gas (nitrogen, &#8230;) which flushes the second chamber.<br \/> With hollow parts or tubes the carrier gas flushes the inner volume and the testing media surrounds it.<\/p>\n<blockquote><p>Detection limit:<br \/>Range of the norm: approx. 0,05 or 1000 cm<sup>3<\/sup>\/(m<sup>2<\/sup>*d*bar) for films or 0,0005 to 10 cm<sup>3<\/sup>\/(d*bar) for hollow parts. Please contact us for your differing requirements.<\/p><\/blockquote>\n<h2>Required specimen:<\/h2>\n<p>For testing please send us a sample of the approximate size of a sheet of paper (DIN A4, 210*297 mm).<\/p>\n<p>For non flat specimens: please send after consulting with us.<\/p>\n<p>Scope of the standard: 50 or 100 cm<sup>2<\/sup> active area for films.<\/p>\n<p>The specimens shall be uniform in thickness, representative for the material and free of pinholes and folds.<\/p>\n<p>On request we measure your sample thickness according to DIN 53534.<\/p>\n<p>We recommend the measurement of three independent samples per test (minimum number not regulated by the standard). Our standard is to measure samples of 20 \u00b5m &#8211; 3 mm, others on request. We perform the preparation of the samples for you.<\/p>\n<p>For different test gases and type of samples we use different sized samples. If you want to conduct the cutting of the specimens, please contact us for the required dimensions.<\/p>\n<p>For sensitive coating tests sometimes it makes sense to prepare the sample first followed by coating afterwards.<\/p>\n<p>Please inform us, if your samples tend to mechanical failure under applied pressure (of the test gas or the sealings).<\/p>\n<h2>Testing medium:<\/h2>\n<p>The standard provides only O<sub>2<\/sub> but with other detectors it is possible to work with CH<sub>4<\/sub>, N<sub>2<\/sub>, Ar, He, H<sub>2<\/sub>, Cl<sub>2<\/sub> or other gases.<\/p>\n<p>Our testing cells are nearly universal in usage due to noncorrosive construction.<\/p>\n<p>Please contact us for special applications. The testing method is normally limited to substances or mixtures which contain substances with very skewing permeation rates.<\/p>\n<h2>Test conditions:<\/h2>\n<p>Temperature and gas pressure are not regulated by the standard.<\/p>\n<p>Mecadi&#8217;s possible testing temperatures:<\/p>\n<ul>\n<li>Standard &#8211; 50 \u00b0C up to +150 \u00b0C, other temperatures on request.<\/li>\n<\/ul>\n<p>Temperature tolerance possible with Mecadi equipment:<br \/>Better than +\/- 0,1 K (Experience shows that +\/- 1\u00b0K tolerance leads to permeation rate scattering up to 20 %).<\/p>\n<p>Mecadi&#8217;s possible testing pressures:<\/p>\n<ul>\n<li>Standard: until 100 bar, others on request.<\/li>\n<\/ul>\n<p>Please contact us for information about special effects and requirements for the samples at high pressures.<\/p>\n<p>Also possible are temperature profiles (nonisothermic measurements) for the determination of morphology changes and the influence of media and pressure on polymer properties.<\/p>\n<p>Based on this method, Mecadi offers further examination to determine gas solubilities (sorption and desorption), diffusion coefficients and the measurement of break through times through barriers.<\/p>\n<p>Furthermore interactions between media and polymer can be investigated. So the predictions according resitance, physical and chemical reactions under process conditions can help in the selection process of materials.<\/p>\n<p>You find this article here as a PDF.
