1030S Solids Analysis Module

1030S Solids Analysis Module

 

Features


Combusts solid materials soils, sludges, 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.

 

Description


The 1030S Solids Module is a sample preparation module enabling the analysis of the total organic carbon (TOC) or total carbon (TC) content in solid materials. The 1030S module is operated in conjunction with an Aurora 1030W or 1030C TOC analyzer.

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).
