Carbon analysis

Infrared spectrometry offers a sensitive analytical method to determine various carbon modifications such as
 

  • Total carbon (TC)
  • Total inorganic carbon (TIC), CO2
  • Total organic carbon (TOC)
  • carbide-bound carbon, free carbon

in highly diverse matrices like, for example, soils and rocks, oxidic raw and processed materials, carbides, and others.

 

Our test methods for the analysis of carbon

  • DIN ISO 10694:1996-08 - Soil quality - Determination of organic and total carbon after dry combustion (elementary analysis)
  • DIN EN 13137:2001-12 -  Characterization of waste - Determination of total organic carbon (TOC) in waste, sludges and sediments
  • DIN EN 13639:2002-07 - Determination of total organic carbon in limestone
  • DIN EN 13639 Berichtigung 1:2006-09 - Determination of total organic carbon in limestone
  • DIN EN ISO 21068-2:2008-12 - Chemical analysis of silicon-carbide-containing raw materials and refractory products - Part 2: Determination of loss on ignition, total carbon, free carbon and silicon carbide, total and free silica and total and free silicon 
  • DIN 51075, Teil 2:1984-03 - Prüfung keramischer Roh- und Werkstoffe, Chemische Analyse von Siliciumcarbid, Direkte Bestimmung von freiem Kohlenstoff
  • DIN 51075, Teil 3:1984-03 - Prüfung keramischer Roh- und Werkstoffe, Chemische Analyse von Siliciumcarbid, Bestimmung des Gehaltes an Gesamtkohlenstoff
