Simulated Charcoal or Zeolite Gamma Cartridge Standards\u2014EG-CH:<\/b><\/p>\r\n

The activity is uniformly distributed between two polyimide films and placed under the screen of a 1\u201d x 2.25\u201d (25.4 mm x 57.2 mm) separable plastic charcoal cartridge (surface loaded). This configuration simulates a face loaded charcoal cartridge.<\/p>\r\n

Face Loaded: The activity is uniformly distributed between two polyimide films and placed under the screen of a 1\u201d x 2.25\u201d (25.4 mm x 57.2 mm) plastic charcoal cartridge (surface loaded).<\/p>\r\n

Uniform Distribution: The activity is uniformly distributed within the charcoal or zeolite filling of the cartridge.<\/p>\r\n

An aluminum metal cartridge is also available upon request. The standard activity for all configurations is 3.7 kBq (0.1 \u00b5Ci). Sources are NIST traceable for contained activity.<\/p>\r\n ","link":{"title":"Back to overview - Geometry Sources","url":"https:\/\/www.ezag.com\/de\/produkte\/isotope-products\/isotrak-calibration-sources\/reference-sources\/geometry-sources\/","target":""},"link2":"","file":"","btnausrichtung":"align-left","id":"","textrahmen":false,"twocoloum":false,"tableshort":false,"abstand_oben":true,"abstand_unten":false}],"thumb":"","kurzbeschreibung":""},"_links":{"self":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/398","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/comments?post=398"}],"version-history":[{"count":12,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/398\/revisions"}],"predecessor-version":[{"id":8470,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/398\/revisions\/8470"}],"up":[{"embeddable":true,"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/pages\/165"}],"wp:attachment":[{"href":"https:\/\/www.ezag.com\/de\/wp-json\/wp\/v2\/media?parent=398"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
