CHNS/O Elemental Analyzer: How does it work?

Elemental Analyzer

What is an elemental analyzer? 

An elemental analyzer is a piece of equipment that identifies the elemental or isotopic properties of a sample, such as soil, waste and drinking water, minerals or chemical compounds. It is used to analyze quantitatively and qualitatively the levels of carbon, hydrogen, sulfur and oxygen in materials, which find application types in the field of pharmaceuticals, polymers, chemicals, environmental and energy.

How does an elemental analyzer work?

A sample of 1-3mg will be placed into the apparatus which can deal with a varying range of samples. Depending on the mode of the analyzer, will determine the process used and the temperature the furnace runs at. These modes include CHNS (combustion method) which will run at 975°c and O (pyrolysis method) which runs at 1000°c. Once a sample has been combusted/pyrolyzed through these methods, they are ready for analysis. Smaller samples are able to go straight into the machine, whereas bulk samples will have to be homogenized as preparation before entering the elemental analyzer. 

Our elemental analyzer services include: 

  • Identification of unknown compositions in plastic, biodegradable materials, films, packaging products, oils, water, soil and compost 
  • Carbon to nitrogen ratio
  • Total Organic Carbon Analysis (TOC)
  • Total inorganic carbon Analysis (TIC)

 As part of our new analytical lab, we are introducing an elemental analyzer for various testing. Our network of specialists has years of industry experience within polymers, materials, and packaging. For more information, contact us here or call us on +44(0) 1324 489 182 to talk to one of our experts.
