L\u2019instrument polyvalent pour la diff\u00e9renciation du carbone en fonction de la temp\u00e9rature dans les solides<\/h2>\n

La d\u00e9termination du carbone organique total (COT) dans les solides a r\u00e9cemment gagn\u00e9 en importance, non seulement pour l\u2019\u00e9valuation des d\u00e9chets, mais \u00e9galement pour l\u2019analyse et le suivi de la qualit\u00e9 des sols.
\nLe nouveau soli TOC cube, un analyseur de COT, permet de mesurer non seulement le carbone organique total (TOC) et le carbone inorganique total (TIC), mais aussi le carbone oxydable r\u00e9siduel (ROC).<\/p>\n

En plus de la d\u00e9termination traditionnelle du COT par les m\u00e9thodes d'acidification directe et par soustraction, le soli TOC cube propose \u00e9galement une programmation de la temp\u00e9rature. Cette fonctionnalit\u00e9 permet d\u2019\u00e9viter la pr\u00e9paration laborieuse des \u00e9chantillons ou l\u2019utilisation d\u2019acides.<\/p>\n

Performance analytique in\u00e9gal\u00e9e<\/strong><\/h6>\n

Dans la programmation de la temp\u00e9rature, une r\u00e9gulation pr\u00e9cise et ajustable est cruciale pour garantir des mesures reproductibles. Le soli TOC cube mesure la temp\u00e9rature directement au niveau du creuset, ce qui \u00e9limine les interf\u00e9rences thermiques potentielles. De plus, l\u2019int\u00e9gration d\u2019un catalyseur de postcombustion assure une oxydation compl\u00e8te, m\u00eame pour les \u00e9chantillons \u00e0 forte teneur en carbone, garantissant ainsi une qualit\u00e9 de mesure \u00e9lev\u00e9e et constante.<\/p>\n

Pr\u00e9paration des \u00e9chantillons simplifi\u00e9e<\/strong><\/h6>\n

Le soli TOC cube permet une analyse fiable d\u2019\u00e9chantillons de taille importante, de l\u2019ordre du gramme. Il suffit de peser les \u00e9chantillons solides dans des creusets r\u00e9utilisables, de les placer dans le passeur d\u2019\u00e9chantillons, puis de lancer la s\u00e9quence. Cet instrument est donc parfaitement adapt\u00e9 \u00e0 l\u2019analyse pr\u00e9cise d\u2019\u00e9chantillons non homog\u00e8nes. La mesure du COT selon la norme DIN 15936<\/strong> est particuli\u00e8rement simple : les \u00e9chantillons sont acidifi\u00e9s directement dans le creuset en c\u00e9ramique, s\u00e9ch\u00e9s, puis introduits dans l\u2019instrument. Le processus est \u00e0 la fois rapide, simple et fiable.<\/p>\n

Une analyse fiable<\/strong><\/h6>\n

Le logiciel offre la possibilit\u00e9 d\u2019utiliser des m\u00e9thodes pr\u00e9d\u00e9finies ou de programmer librement les paliers de temp\u00e9rature et les temps de maintien. L\u2019int\u00e9gration des pics est effectu\u00e9e automatiquement, tout en permettant une v\u00e9rification manuelle. Cela garantit des r\u00e9sultats pr\u00e9cis, m\u00eame pour les analyses les plus complexes.<\/p>\n

Une flexibilit\u00e9 incomparable<\/strong><\/h6>\n

Le soli TOC cube peut distinguer les diff\u00e9rentes formes de carbone en utilisant soit la programmation de la temp\u00e9rature, soit une combinaison de la programmation de la temp\u00e9rature et de la commutation des gaz. En un seul programme, il peut d\u00e9terminer le COT, le COR et le COV. Il est \u00e9galement possible d'utiliser la m\u00e9thode classique d'acidification, de s\u00e9chage et de mesure du COT \u00e0 temp\u00e9rature constante.<\/p>\n

M\u00e9thode de mesure :<\/strong><\/h6>\n

Le soli TOC cube se distingue par une mont\u00e9e en temp\u00e9rature dans une atmosph\u00e8re oxyg\u00e9n\u00e9e allant jusqu'\u00e0 900\u00b0C pour la d\u00e9termination du TOC, du ROC et du TIC dans les solides, conform\u00e9ment \u00e0 la norme DIN 19539.<\/strong>Il permet \u00e9galement de changer de gaz, combinant ainsi des gaz porteurs oxydants et non oxydants dans un seul parcours, ce qui permet de s\u00e9parer le ROC et le TIC. La combustion catalytique isotherme est propos\u00e9e pour la d\u00e9termination du COT dans les solides, en accord avec la norme EN 15936.<\/strong>Une fonction optionnelle permet \u00e9galement la d\u00e9termination simultan\u00e9e du TN et de l'ECD.<\/p>\n

 <\/p>\n

Sp\u00e9cifications de l'analyseur TOC :<\/strong><\/h3>\n

Large plage de concentrations<\/strong>
\nDe quelques ppm jusqu'\u00e0 100% ou 50 mg de carbone et 20 mg (0-15%) d'azote absolu.<\/p>\n

Pr\u00e9paration et manipulation des \u00e9chantillons simplifi\u00e9es<\/strong>
\nSans pr\u00e9paration particuli\u00e8re, tous les types d'\u00e9chantillons solides sont pes\u00e9s dans des creusets en acier ou en c\u00e9ramique (masse de l'\u00e9chantillon jusqu'\u00e0 3 g).<\/p>\n

Enti\u00e8rement automatique :<\/strong>
\nFonctionnement automatis\u00e9 et sans surveillance gr\u00e2ce \u00e0 l\u2019autosampler int\u00e9gr\u00e9 \u00e0 89 positions et au contr\u00f4le PC sous Windows\u00ae. De plus, un logiciel optionnel conforme \u00e0 la norme 21 CFR Part 11<\/strong> est disponible.<\/p>","protected":false},"excerpt":{"rendered":"
