Matrix-onafhankelijke bepaling van N en C op trace-niveau<\/h2>\n

Organische Elementaire Analyzer<\/strong><\/h3>\n

De UNICUBE trace is een organische elementaire analyzer<\/strong> die gespecialiseerd is in het meten van lage stikstof- en koolstofconcentraties in vaste stoffen en zeer viskeuze vloeistoffen. <\/strong>De detectielimiet bedraagt 10 mg\/kg. Het systeem is gespecialiseerd in stikstof- en koolstofbepaling volgens de Dumas-methode. Deze methode verwijdert storende gassen tijdens de reductie en detecteert doelgassen met een thermische geleidbaarheidsdetector. Zo combineert de UNICUBE trace de voordelen van de matrix-onafhankelijke Dumas-methode met hoge gevoeligheid.<\/p>\n

Bij de UNICUBE trace vindt de monsterontsluiting plaats door katalytische verbranding bij 950 \u00b0C,<\/strong> waarbij stikstof- en koolstofverbindingen in het monster worden omgezet in een mengsel van oxiden en N2. Dit mengsel gaat vervolgens door een reductiebuis, waar koolstofverbindingen worden omgezet in CO2 en stikstofverbindingen in N2. Na het verwijderen van andere verbrandingsproducten zoals H2O en SO2, worden de CO2- en N2-gassen gedetecteerd met behulp van thermische geleidbaarheidsdetectie.<\/p>\n

Het systeem biedt eenvoudig, onderhoudsarm gebruik.\nDankzij matrix-onafhankelijke analyse kunt u een standaard \u2018universele\u2019 kalibratie gebruiken voor elk monstertype. De voordeur van de analyzer opent voor uitstekende toegang bij het vervangen van verbruiksartikelen. Het wisselen van de verbrandings- en reductiebuis is eenvoudig dankzij de uitschuifbare oven.<\/p>\n

 <\/p>\n

Specificaties van de organische elementaire analyzer:<\/strong><\/h3>\n

Verbranding bij hoge temperatuur:<\/strong>
\nUNICUBE trace biedt kwantitatieve monstervoorbereiding tot 1.200 \u00b0C, ondersteund door 10 jaar garantie op de oven. Het zorgt voor volledige omzetting van alle stikstofcomponenten naar N\u2082. Het systeem gebruikt jet-injectie van zuurstof direct op het monster, waardoor een hoge zuurstofconcentratie op het verbrandingspunt ontstaat. Dit minimaliseert het gasverbruik.<\/p>\n

Grootste weegbereik:<\/strong>
\nHet weegbereik dekt zowel microtoepassingen (minder dan 1 mg) als macrotoepassingen (ongeveer 1 g bodem), afhankelijk van de vereisten. Analyse van maximaal 20 mg organische stof is mogelijk.<\/p>\n

Grootste dynamische bereik van elementconcentraties en -verhoudingen:<\/strong>
\nUNICUBE trace ondersteunt elementconcentraties en verhoudingen tot 50 mg C abs. of 10 mg N abs. of 100%, afhankelijk van analysemode en monstermatrix. Het systeem biedt een detectielimiet van 10 ppm voor zowel N als C.<\/p>\n

Multipoint-calibratie:<\/strong>
\nBiedt maandenlang matrix-onafhankelijke stabiliteit.<\/p>\n

PC-gebaseerde instrumentbediening<\/strong>
\nVolledige digitalisering maakt bediening op afstand via een standaard PC mogelijk, voor perfecte resultaten, zelfs bij onbekende of sterk variabele monstermatrices. Inclusief ge\u00efntegreerde standaard monsterwisselaar voor 120 monsters en 21 CFR Part 11-functionaliteit.<\/p>\n

E\u00e9n eenvoudig instrument voor alle toepassingen:<\/strong>
\nUNICUBE trace elimineert dure speciale katalysatoren, vereenvoudigt asverwijdering uit de verbrandingsbuis en biedt duurzame componenten voor lage eigendomskosten.<\/p>\n

Schoon, veilig en snel:<\/strong>
\nElke analyse duurt slechts enkele minuten en gebruikt helium als draaggas, zonder agressieve of giftige chemicali\u00ebn.<\/p>\n

Eenvoudige installatievereisten:<\/strong>
\nUNICUBE trace heeft slechts 48 \u00d7 55 cm werkbankruimte nodig en werkt op \u00e9\u00e9n stroomaansluiting (230, 110 of 100 V) en twee gassen, voor langdurige onderhoudsvrije werking.<\/p>","protected":false},"excerpt":{"rendered":"
