1030S Solids Analysis Module

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.
