1030S TOC Solids Module The 1030S Solids Module is a sample preparation module operated in conjunction with an Aurora 1030 TOC Analyzer that combusts solid materials for analysis of the total carbon (TC) or TOC content. 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 (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 TIC-free sample is placed on the lift mechanism and raised into the into the combustion tube of the 1030S (1). 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 (2). 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 (3).
