D\u00e9termination pr\u00e9cise du soufre et de l'azote \u00e0 des concentrations tr\u00e8s faibles<\/h2>\n

L'analyse d'hydrocarbures tels que l'essence, le diesel ou le gaz naturel exige souvent la d\u00e9tection de soufre et d'azote \u00e0 des concentrations extr\u00eamement faibles. Cet analyseur de soufre et d'azote s'appuie sur le succ\u00e8s du syst\u00e8me d'injection liquide vario trace SN. Il combine une technique de combustion \u00e9prouv\u00e9e \u00e0 un passeur d\u2019\u00e9chantillons nouvellement con\u00e7u.<\/p>\n

Le cube SN trace int\u00e8gre deux canaux complets de combustion et de d\u00e9tection au sein d\u2019un seul analyseur. Un injecteur automatique unique alimente ces deux canaux en r\u00e9alisant des injections distinctes pour chaque analyse. Cette configuration assure des conditions analytiques optimales et permet l\u2019utilisation de catalyseurs sp\u00e9cifiques sans aucun compromis.<\/p>\n

La conception int\u00e9gr\u00e9e r\u00e9duit \u00e0 la fois les co\u00fbts et l\u2019encombrement par rapport \u00e0 l\u2019utilisation de deux analyseurs distincts. Elle simplifie \u00e9galement les op\u00e9rations gr\u00e2ce \u00e0 un contr\u00f4le \u00e9lectronique centralis\u00e9 et \u00e0 un traitement automatis\u00e9 des donn\u00e9es. L\u2019appareil est enti\u00e8rement conforme aux normes ASTM D 5453, D 6667, D 4629 et DIN ISO 20846.<\/p>\n

Sp\u00e9cifications de l\u2019analyseur soufre et azote :<\/strong><\/h3>\n

M\u00e9thode de mesure<\/strong>
\nLe trace SN cube permet une combustion \u00e0 haute temp\u00e9rature dans le gaz porteur jusqu'\u00e0 1,150 \u00b0C. l autorise l\u2019injection directe d\u2019\u00e9chantillons liquides dans des ports d\u00e9di\u00e9s, assurant ainsi une d\u00e9termination s\u00e9par\u00e9e et pr\u00e9cise de l\u2019azote et du soufre.<\/p>\n

Deux instruments en un<\/strong>
\nLe trace SN cube int\u00e8gre deux canaux de combustion et de d\u00e9tection totalement ind\u00e9pendants : un pour le soufre et un pour l\u2019azote. Cette configuration offre des conditions analytiques optimales et des catalyseurs d\u00e9di\u00e9s \u00e0 chaque analyse, procurant tous les avantages de deux analyseurs distincts sans co\u00fbts ni encombrement suppl\u00e9mentaires.<\/p>\n

M\u00e9thodes d'injection efficaces<\/strong>
\nL\u2019instrument accepte des volumes d\u2019injection allant jusqu\u2019\u00e0 20 \u00b5l pour les liquides et 20 ml pour les gaz. Gr\u00e2ce \u00e0 des temps d\u2019injection rapides, il assure une combustion compl\u00e8te, sans r\u00e9sidus, et produit des pics particuli\u00e8rement nets.<\/p>\n

Technique purge and trap<\/strong><\/p>\n

Cette option permet de d\u00e9terminer des concentrations tr\u00e8s faibles de soufre, m\u00eame lorsque les niveaux d\u2019azote sont \u00e9lev\u00e9s.<\/p>\n

D\u00e9tection haute sensibilit\u00e9<\/strong>
\nL\u2019instrument utilise les m\u00e9thodes de d\u00e9tection CLD et fluorescence UV, en conformit\u00e9 totale avec les normes ASTM, garantissant des r\u00e9sultats pr\u00e9cis et fiables.<\/p>\n

Large plage de mesures<\/strong>
\nLes niveaux de S et N peuvent \u00eatre mesur\u00e9s entre 0 et 1 000 ppm. Les limites de d\u00e9tection sont fix\u00e9es \u00e0 6 ppb pour le soufre et 15 ppb pour l\u2019azote.<\/p>\n

Conformit\u00e9 aux normes industrielles<\/strong>
\nLe syst\u00e8me fonctionne selon des standards v\u00e9rifi\u00e9s, notamment : ASTM D 6920, ASTM D 4629, ASTM D5453, ASTM D6667, DIN ISO 51444, ASTM D6069 et DIN ISO 20846.<\/p>","protected":false},"excerpt":{"rendered":"
