    • The invention relates to a device and a method for determining the permeation rate of at least one permeate through an element (1) that forms a diffusion barrier. The aim of the invention is to permit extremely low permeation rates to be determined with sufficient measuring sensitivity, accuracy and justifiable time expenditure. In the device according to the invention, at least some sections of the element (1) that produces the permeation rate form a partition between a permeate chamber (2,1) and a detection chamber (2,2), or between a permeate chamber and a connection (10) to a detection chamber (2,2). A gas containing at least one permeate, or a fluid of this type, or a gaseous permeate is fed to the permeate chamber (2.1) or is contained in the latter. Radiation from at least one laser light source (4), with a wavelength corresponding to an absorption wavelength of the relevant permeate, is directed through the detection chamber (2,2) in the form of a laser beam onto at least one optical detector (5) in order to determine the permeation rate at an absorption wavelength of the permeate.
    • 本发明涉及一种装置和方法,用于通过一个渗透势垒形成元件(1)来确定至少一个渗透物的渗透速率。 本发明的目的是创造机会,允许有足够的灵敏度,准确度和以合理的成本可被确定极少渗透。 在于,在区域至少形成一个渗透形成元件(1),一个渗透室(2,1)和一个检测室(2,2)或一个终端(10),以检测腔室(2,2)之间的隔壁的本发明的装置。 在这种情况下,渗透室(2.1)被馈送到含气体的至少一个渗透物或这样的液态或气态渗透物或包含在其中。 由于该检测室(2,2)被暴露于辐射的至少一个激光光源(4),其具有对应于相应的渗透物的吸收波长的波长,作为激光束的至少一个光学检测器(5)上,用于确定在所述渗透物的吸收波长的渗透速率, 执导。
