ELEMENTAL ANALYSIS

This technique gives the total contents of carbon, hydrogen, nitrogen and sulphur for a broad range of samples, with organic or inorganic origin, solids or liquids. A sample is burned in an excess of oxygen, and the product gasses (CO2, H2O, SO2 and N2) are transported with a carrier gas (He) through a reduction tube and, subsequently, are selectively separated in chromatography columns to, finally, be desorbed by temperature. Once the simple gases are desorbed, these are detected by a Thermal Conductivity detector, which gives an electrical signal proportional to the concentration of the gases in the sample.

 

Applications

The fields where this technique can be used are several, from the fossil fuels analysis (carbon, coke, gasoline, mineral oils, etc) to the pharmaceutical and fine chemical industry, including soils, food industry, ceramics, etc.

 

Equipment

 

 

  • Elemental Microanalyzer Thermo Finningan Flash 1112 Series

 

 

 

 

 

  • Elemental CHNS Microanalyzer, with Micro TruSpec detection system from LECO. This system utilizes a combination of flow-through carrier gas and individual, highly selective infrared (IR) and thermal conductivity detectors resulting in simultaneous determination of CHNS in less than four minutes. This equipment has been acquired with co-financing from the Generalitat Valenciana through subsidies for the promotion of the research of the science parks of the universities.

 

 

 

 

 

  • Total Carbon and Nitrogen Analyzer “TruSpec CN” LECO, with Sulphur module. The system has incorporated a sulphur detection module to be used with heterogeneous samples, where weights up to 100 mg can be measured. Sulphur detection involves an aditional combustion. The combustion system works in conjunction with the sulphur module.
