For this purpose, the sample must be previously degassed in order to avoid the desorption of gases or vapors during the analysis. In this way, the LRC carries out a systematic thermal treatment under vacuum or nitrogen flow prior to the analysis, depending on samples&#8217; requirements. For this reason,  it is mandatory that the user provides detailed information on the sample&#8217;s thermal stability in order to avoid any decomposition inside the sample holder.  The average amount of sample required for the analysis is 200 mg, however, 500 mg of the sample is strongly recommended in case the analysis needs to be repeated for any reason.<\/p>\n\n\n\n<p>PS: once the analysis is done, the results are sent by email and the samples can be recovered since the analysis is not destructive.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignleft\"><img loading=\"lazy\" width=\"271\" height=\"300\" src=\"https:\/\/www.ufrgs.br\/lrc\/wp-content\/uploads\/2019\/05\/Tristar-II-Plus-Pic1-271x300.jpg\" alt=\"\" class=\"wp-image-614\" srcset=\"https:\/\/www.ufrgs.br\/lrc\/wp-content\/uploads\/2019\/05\/Tristar-II-Plus-Pic1-271x300.jpg 271w, https:\/\/www.ufrgs.br\/lrc\/wp-content\/uploads\/2019\/05\/Tristar-II-Plus-Pic1.jpg 305w\" sizes=\"(max-width: 271px) 100vw, 271px\" \/><\/figure><\/div>\n\n\n\n<p>Responsible:<\/p>\n\n\n\n<p>Brenda da Rolt Nervis<\/p>\n\n\n\n<p><strong>premium.ads.n2@gmail.com<\/strong><\/p>\n\n\n\n<p>For more information, please, visit:<\/p>\n\n\n\n<p><a href=\"http:\/\/www.iq.ufrgs.br\/ca\/index.php\/servicos\/analise-por-adsorcao-de-nitrogenio\">Central Anal\u00edtica &#8211; Adsor\u00e7\u00e3o\/Dessor\u00e7\u00e3o de N2<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"slide-text-bg2\"><span>The Micrometrics Tristar\u00ae II 3020 analyzer allows the determination of surface area, pore volume, pore size distribution (and many other parameters) of so<\/span><\/div>\n<div class=\"slide-btn-area-sm\"><a href=\"https:\/\/www.ufrgs.br\/lrc\/gas-sorption-analyzer\/\" class=\"slide-btn-sm\">Read More<\/a><\/div>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"_links":{"self":[{"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/pages\/689"}],"collection":[{"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/comments?post=689"}],"version-history":[{"count":2,"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/pages\/689\/revisions"}],"predecessor-version":[{"id":699,"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/pages\/689\/revisions\/699"}],"wp:attachment":[{"href":"https:\/\/www.ufrgs.br\/lrc\/wp-json\/wp\/v2\/media?parent=689"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
