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).
