METROVAC was officially recognized as an accredited calibration laboratory in 2002. Soon this laboratory broadened its accreditation scope to include the metrology of ultra-low flows, including reference leaks and leak detection. These new skills gave the motivation to start a new area of research studying the transport of gases and vapors through cork and desorption of contaminants. Achievements on this subject quickly attracted the attention of cork stopper manufacturers and fruitful collaborations have started.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-d59c0e7 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"d59c0e7\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-d7d3c67\" data-id=\"d7d3c67\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-33 elementor-top-column elementor-element elementor-element-f5e5647\" data-id=\"f5e5647\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-de6ded8 elementor-widget elementor-widget-text-editor\" data-id=\"de6ded8\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"color: #333333;\">Meanwhile, the surface science lab underwent in a collaboration with CERN regarding the study of secondary electron emission from carbon coatings, which are used in the accelerator walls to mitigate the formation of the electron cloud.
