Aurora 1030S Solid Module

Technology: TOC

OI Analytical

Need to analyze total organic carbon (TOC) or total carbon (TC) in solid materials? That’s exactly why we built the 1030S Solids Analysis Module. This sample preparation module is the perfect complement to the Aurora 1030W or 1030C TOC analyzers.


Smartly designed, the compact instrument saves bench space while it is hard at work combusting solid materials, soils, sludge, slurries, and powders for TC and TOC analysis.

Principle of Operation

Total organic carbon (TOC) is determined by manually transferring and weighing a solid sample into a quartz sample cup. The total inorganic carbon (TIC) content is removed from the sample by adding acid and heating to drive off CO2 released from inorganic carbon compounds. In the case of total carbon (TC) analysis, the pre-acidification step to remove TIC content is not required.
The sample cup with the TIC-free sample is placed on the lift mechanism and raised into the combustion tube of the 1030S. The sample is heated to 500° – 900 °C inside the furnace. Organic matter in the sample is oxidized and converted to CO2 which is collected in a one liter capacity gas sampling bag. When the combustion cycle is complete an aliquot of the CO2 sample gas is transferred to the NDIR detector in the Aurora 1030 analyzer for measurement of the mass of carbon in the sample.

1030S Features:

  • Combusts solid materials soils, sludge, slurries, and powders for TC and TOC analysis
  • Interfaces with Aurora 1030 TOC analyzer allowing analysis of both solid and liquid samples using a single instrument
  • Gas sampling device (patent pending) collects carbon dioxide (CO2) from sample combustion for quantitation and analysis of intra-sample replicates
  • Compact vertical design saves laboratory bench space
